Answer:
The steps to do this :
[tex]2(g - h) = b + 4[/tex]
[tex]g - h = \frac{b + 4}{2} [/tex]
[tex]g = \frac{b + 4}{2} + h[/tex]
[tex]g = \frac{b}{2} + \frac{4}{2} + h[/tex]
[tex]g = \frac{b}{2} + 2 + h[/tex]
2(g - h)=b + 4
Use the distributive property on the left side:
2g - 2h = b +4
Add 2h to both sides:
2g = 2h + b + 4
Divide both sides by 2:
g = (2h + b + 4)/2
Simplify:
g = b/2 + 2 + h ( note the order of h, 2 and b/2 can be different)

Answer:
12 baskets
Step-by-step explanation:
We solve this question using the Greatest Common Factor method.
We are told that:
There are
24 bottles of shampoo
36 tubes of hand lotion
60 bars of soap.
The same number of each item should be in each basket.
The greatest number of baskets is calculated as follows:
Step 1
We find the factors of 24, 36, 60
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Step 2
We Identify the number that is greatest and common amongst 24, 36 and 60
This is 12.
Then the greatest common factor is 12
Therefore, the greatest number of baskets is 12 baskets

You have been saving nickels, dimes, and quarters in a jar for about a year. You decide to see how much money you've saved up. When you get everything counted it turns out you have 361 total nickels, dimes, and quarters worth a total of $41.45. You think is is odd that you have exactly twice as many dimes as quarters. Find the number of each coin. Number of Nickels: Number of Dimes: Number of Quarters:
Answer:
x = number of nickels = 127
y = number of dimes = 156
z = number of quarters = 78
Step-by-step explanation:
Let
x = number of nickels
y = number of dimes
z = number of quarters
Total worth of the coins = $41.45
Total number of coins = 361
x + y + z = 361 (1)
dime = $0.1,
nickel = $0.05
quarter = $0.25
0.05x + 0.1y + 0.25z = 41.45 (2)
twice as many dimes as quarters.
y = 2z
Substitute y = 2z into (1) and (2)
x + 2z + z = 361
0.05x + 0.1(2z) + 0.25z = 41.45
x + 3z = 361
0.05x + 0.2z + 0.25z = 41.45
x + 3z = 361 (3)
0.05x + 0.45z = 41.45 (4)
Multiply (4) by 20
x + 3z = 361 (3)
x + 9z = 829 (5)
Subtract (3) from (5)
9z - 3z = 829 - 361
6z = 468
Divide both sides by 6
z = 468 / 6
= 78
z= 78
Recall,
y = 2z
= 2(78)
= 156
y = 156
Substitute the value of y and z into
x + y + z = 361
x + 156 + 78 = 361
x + 234 = 361
x = 361 - 234
= 127
x= 127
x = number of nickels = 127
y = number of dimes = 156
z = number of quarters = 78

Plot the points A(-4,-6), B(-10, -10), C(-3, -8) on the coordinate axes below. State the coordinates of point D such that A, B, C, and D would form a parallelogram. (Plotting point D is optional.)
Check the picture below.
Coordinates of point D of parallelogram = (3 , -4)
What is parallelogram?A parallelogram is quadrilateral in which opposite angles are equal and opposite sides of the quadrilateral are equal and parallel to each other.
The Diagonals in the parallelogram bisect each other.
Given points
A(-4,-6), B(-10, -10), C(-3, -8)
Let the 4th point D = (x , y)
In a parallelogram, diagonals bisect each other.
midpoint of BD = midpoint of AC
If two points are (x₁ , y₁) and (x₂,y₂)
then midpoint = {(x₁+x₂)/2 , (y₁+y₂)/2}
midpoint of AC = {(-4 + -3)/2 , (-6 + -8)/2}
= {-7/2 , -7}
midpoint of BD = {(-10 + x)/2 , (-10 + y)/2}
Now,
midpoint of BD = midpoint of AC
{-7/2 , -7} = {(-10 + x)/2 , (-10 + y)/2}
Comparing both sides
taking x -coordinate
(-10 + x)/2 = -7/2
Multiplying with 2 on both sides
-10 + x = -7
x = 3
taking y -coordinate
(-10 + y)/2 = -7
Multiplying with 2 on both sides
-10 + y = -14
y = -14 + 10
y = -4
Point D (x , y) = (3, -4)
Hence, (3, -4) are the coordinates of point D of parallelogram.

much area does she need to plant? Find the cost of fencing it with barbed wire at the
rate of Rs 20 per metre leaving a space 3m wide for a gate on one side.
pls answer ASAP
The fence would cover the perimeter of the triangle.
The perimeter is the sum of the 3 sides:
120 + 80 + 50 = 250 meters.
There will be a 3 meter space for the gate, so subtract 3:
250 - 3 = 247 meters of fence is needed.
Now multiply the amount of fences needed by the price per meter:
247 x 20 = Rs 4,490

the sum
of the square of two consecutive
odd intergers is
290. Find the integers.
Answer:
11 & 13 or - 13 & - 11
Step-by-step explanation:
Let the integers are a - 1 and a + 1.
Sum of squares = 290
=> (a - 1)² + (a + 1)² = 290
=> a² + 1² - 2a + a² + 1² + 2a = 290
=> 2a² + 2 = 290
=> 2(a² + 1) = 290
=> a² + 1 = 290/2 = 145
=> a² = 145 - 1 = 144
=> a = ± √144 = ± 12
If a = + 12, numbers are
12 - 1 = 11 & 12 + 1 = 13
If a = - 12, numbers are
- 12- 1 = - 13 & - 12 + 1 = - 11
A committee consisting of 4 faculty members and 5 students is to be formed. Every committee position has the same duties and voting rights. There are 8 faculty members and 13 students eligible to serve on the committee. In how many ways can the committee be formed?
Answer:
Step-by-step explanation:
This question bothers on combination. combination has to do with selection.
If 4 faculty members are chosen from total of 8 faculty members, this can be done in 8C4 number of ways.
8C4 = 8!/(8-4)!4!
8C4 = 8!/4!4!
8C4 = 8*7*6*5*4!/4!*4*3*2
8c4 = 8*7*6*5/24
8C4 = 7*5*2
8C4 =70 ways
Similarly, 5 students are to be selected from a pool of 13 students, this can be done in 13C5 number of ways.
13C5 = 13!/(13-5)!5!
13C5 = 13!/8!5!
13C5 = 13*12*11*10*9*8!/8!*5*4*3*2
13C5 = 13*12*11*10*9/120
13C5 = 1,287 ways
The total number of ways the committee can be formed is 8C4 * 13C5 = 70*1287
The total number of ways the committee can be formed is 90,090 ways

Pls help me with this questions
Answer:
1. First, we need to find the area of the rectangle, then subtract the non-shaded region from the total of the rectangle's area.
Area of rectangle formula;
A = LW
Where 'L' represents the length, and 'W' represents the width.
Plug in your values:
A = LW
A = 8(13)
A = 104, now that we've found the area of this total rectangle, we need to find the area of the triangle and subtract that from the area of the rectangle.
Formula for area of triangle;
A = BH x 1/2
Where 'B' represents the base, and 'H' represents the height and 1/2 is just 1/2.
But, if we look at this triangle we can see that we don't have the base.
So what we have to do is subtract the given side lengths beside it (which you add up) from the total width.
Given length beside unknown base: 4 and 4
So, (4 + 4) = 8, and the total width is 13.
So: 13 - 8 = 5, 5 is our base.
Now we plug these into our formula:
A = BH x 1/2
A = 5(6) x 1/2
A = 30 x 1/2
A = 30/2, which equals to 15.
Now we subtract the non shaded region(triangle) from the shaded region(total area of rectangle).
104 - 15 = 89 meters.
2. In this figure, we find the area of the whole triangle, not considering the small empty vertical-positioned rectangle to the bottom left corner.
Let's find the total base and total height.
As we can see, in the bottom triangle the height is 4, the other triangle has a height of 5. Combine these to get (4 + 5) = 9 is our total height of the whole triangle.
Now we find the base, 5 is the base of the bottom triangle and the other triangle has a base of 2, combine these to get: (5 + 2) = 7 is the total base of the whole triangle.
Now plug these into our formula of area of triangle;
A = BH x 1/2
A= 7(9) x 1/2
A = 63/2
A = 31.5, is the area of the whole triangle.
Now let's find the area of the empty rectangle to our bottom left corner.
Our length is 4, our width is 2.
A = LW
A = 4(2)
A = 8
Now subtract the empty rectangle's area from the total area of the triangle:-
31.5 - 8 = 23.5 inches.
3. We can see that in this figure, there is an empty semi circle(that has no area) apart of a square.
So to find the area of the unfinished square, we find the area of the semi circle and subtract it from the total area of the square.
Formula for area of a circle:
A = π[tex]r^{2}[/tex]
Where 'π' represents pi aka (22/7 or 3.14), and 'r' represents the radius which is being squared.
But if we were to find the area of a semi circle, we would have to divide the whole formula of a regular circle by 2.
So, A = π[tex]r^{2}[/tex]/2
Now, we plug in the values showing in the diagram into our equation.
Though, since we are given a diameter of 6, we need to find the radius which is 1/2(half) of the diameter.
SO,
1/2 x 6 = 3.
Now that we have our radius, we can finally plug this into our equation:-
A = π[tex]r^{2}[/tex]/2
A = 3.14(3^2)/2
A = 3.14(9)/2
A = 28.26/2
A = 14.13, is our area of the semi circle.
Now we have to find the total area of the square, which we easily just multiply the two lengths.
6(length) x 6(width)
= 36, is the area of the total square.
Now we subtract the area of the semi circle from the area of the total square:
36 - 14.13 = 21.87 feet.
4. To find the area of this, we must split the figure into two shapes, a rectangle and a semi circle.
Using the formulas we applied to our past problems;
(Rectangle)
A = LW
A = 20(8)
A = 160, is the area of the rectangle
Now the semi circle (ignore the 12.56, because it's just the circumference):
We have to find the radius, (1/2 x diameter), so: (1/2 x 8) = 4 is our radius.
A = π[tex]r^{2}[/tex]/2
A = 3.14(4^2)/2
A = 3.14(16)/2
A = 50.24/2
A = 25.12, is the area of the semi circle.
Now we add the two areas,
160 + 25.12 = 185.12 feet.
5. We split this figure into two shapes, a rectangle and a triangle.
Using the formulas we applied earlier to our past problems.
(Rectangle)
A = LW
A = 14(12)
A = 168, is the area of the rectangle.
(Triangle)
A = BH x 1/2
A = 8(12) x 1/2
A = 96 x 1/2
A = 96/2
A = 48, is the area of the triangle.
Now we add these areas;
168 + 48 = 216 centimetres.

The quadrilateral with vertices (0, 0), (0, 4), (8, 4) and (8,0) makes the rectangle.
What is rectangle?A rectangle is a part of a quadrilateral, whose sides are parallel to each other and equal.
The given points are,
(0, 0), (0, 4), (8, 4) and (8,0).
To determine the section for the quadrilateral,
Find distance between points.
The distance between two points A(x₁, y₁) and B(x₂, y₂)
Distance
= √(x₂ - x₁)² + (y₂ - y₁)²
The distance between (0, 0) and (0, 4)
= √(0-0)² + (4-0)² = √(0)² + (4)² = √(4)² = 4
The distance between (0, 4) and (8, 4)
= √(8-0)² + (4-4)² = √(8)² + (0)² = √(8)² = 8
The distance between (8, 4) and (8, 0)
= √(8 - 8)² + (0 - (4))² = √(0)² + (4)² = √(4)² = 4
The distance between (8, 0) and (0, 0)
= √(0 - 8)² + (0- 0)² = √(-8)² + (0)² = √(8)² = 8
Since, the opposite sides are equal,
Therefore, the quadrilateral is rectangle.
