Answer:
The answer is 10
Step-by-step explanation: So first we divided 15 by 3 which is 5. Then we times 4 and 5 which is 20. 10+x=20, so x = to 10
Answer:
x = 10
Step-by-step explanation:
4/3 = (x+10)/15
Using cross products
15*4 = 3*(x+10)
60 = 3(x+10)
Divide each side by 3
60/3 = 3/3(x+10)
20 = x+10
Subtract 10 from each side
20-10 = x+10-10
10 = x

Step-by-step explanation:
Answer:
3/8
Step-by-step explanation:
3х +2y = 12 + у
4y — 7t = 10
Solving systems of equations
numbers 3x + 2y = 12
y = x + 1
Substitution Method
Since y is already isolated in the second equation we can use that value, to substitute for y in the first equation.
3x + 2 (x + 1) = 12
3x + 2x + 2 = 12
5x = 12 − 2
5x = 10
x = 2
Substitute the computed value of x to the second equation to determine the value of y.
y = 2 + 1
y = 3
Elimination Method
3x + 2y = 12
x − y = −1
Multiply the second equation by 2 to eliminate
x or you can also multiply the second equation by 3 to eliminate y. However since it is easier to multiply by 2, I will follow the first method.
3x + 2y = 12
2x − 2y = −2
Adding the two equations eliminates the y variable.
5x = 10
x = 2
Substitute the computed value of x to the second equation to determine the value of y.
y = 2 + 1
y = 3
Solution Set:
(2,3)
Which equation demonstatres the distributive property?
A. 39 + 9 = 45
B. 39 + 3 = 39(12 + 3)
C. 36 times 9 = 9 times 36
D. (12 + 3)3 = 3(12 + 3)
Answer:
B
Step-by-step explanation:
The distributive property states that:
a(b + c) = ab + ac
Look at the choices:
A: 39 + 9 = 45
There's nothing of this form; in fact, there aren't even any parentheses, so eliminate A.
C: 36 times 9 = 9 times 36
This is saying 36 * 9 = 9 * 36. Again, there aren't any parentheses. Actually, this demonstrates the commutative property.
D: (12 + 3)3 = 3(12 + 3)
There are parentheses, but they're on both sides, so this can't be right, either. In fact, this is the associative property.
By elimination, the answer is thus B.
The rule of distributive property states that [ a(b + c) = ab + ac ].
So, we need to find an answer choice that contains that specific format.
Option A is incorrect because there is nothing to solve for on the right side.
Option B is correct because it contains the same format as the rule stated above.
Option C is incorrect because its the same as [ 36 * 9 = 9 * 36 ] and it's not in the same format as the rule.
Although Option D has half of the format in the rule, it doesn't have the other half containing what it looks like after the distributive property is appplied. So, this is incorrect as well.
Therefore, the answer is B.

Robert wants to buy lights around the edge of his deck the deck is 49feet and 26feet wide how many yards of lights does he need
Answer:
150 feet
Step-by-step explanation:
Assuming the deck is a rectangle, you need to multiply each side by 2 and add them together.
Answer:
50 yards
Step-by-step explanation:
Let l = length, w = width, and P = perimeter in feet. Let x equal perimeter in yards.
To solve this problem, we first need to find the perimeter of the deck.
To do so, use the formula 2l + 2w = P.
Since the deck is 49 feet long and 26 feet wide, plug in 49 for l and 26 for w.
2(49) + 2(26) = P
Evaluating 2*49 and 2*26, the equation becomes 98 + 52 = P.
Evaluating 98 + 52, the equation becomes 150 = P.
The next step in this problem is to convert feet to yards. We know that Robert needs 150 feet of lights. Since there are three feet in a yard, we can use the formula P = 3x to find the amount of yards of lights Robert needs.
Plugging in 150 for P, the equation becomes 150 = 3x.
Dividing both sides by 3, the equation becomes 50 = x.
Therefore, the final answer is 50 yards.

The perimeter of the figure is, 25.12 feet
And, the area of the figure is, 50.24 feet²
What is mean by Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
We have to given that;
The radius of the partial circle with center A is,
⇒ 4 feet.
Now,
We know that;
Perimeter of circle = 2πr
Here, r = 4 feet
⇒ Perimeter of circle = 2πr
⇒ Perimeter of circle = 2 × 3.14 × 4
⇒ Perimeter of circle = 25.12 feet
And, Area of circle = πr²
⇒ Area of circle = 3.14 × 4²
⇒ Area of circle = 50.24 feet²
Thus, The perimeter of the figure is, 25.12 feet
And, the area of the figure is, 50.24 feet²

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
Given that:-
Allison is buying binders for school. Small binders cost $3 each, and large binders cost $5 each. If Allison needs to buy at least 12 binders and has no more than $45 to spend, what is the maximum number of large binders she can buy?From the given data we can form the equation let n1 and n2 are the numbers of the small and the large binders and Sb and Lb are the cost of each binder.
n₁Sb + n₂Lb = 45 ................................1
n₁ + n₂ = 12
Now put the value of n₁ in equation 1.
( 12 - n₂ )3 + 5n₂ = 45
36 - 3n₂ + 5n₂ = 45
2n₂ = 9
n₂ = 4.5
n₂ ≅ 5
Therefore the maximum number of large binders she can buy is 5.

1.) minutes
2.) kilograms
3.) grams
4.) milligrams
5.) seconds
(b) Which of the procedures below would be the best way to find the average mass?
1.) Pick 2 fish from a shallow region of the pond and weigh each of them.
2.) Pick 42 fish from a shallow region of the pond and estimate their masses.
3.) Randomly pick 2 fish from the entire pond and estimate their masses.
4.) Randomly pick 42 fish from the entire pond and weigh each of them.
Answer:
A. 2, 3, and 4
B: 4
Step-by-step explanation:
Average mass is defined as, adding masses of all bodies and then divide by number of bodies.
(a). Kilograms, grams and milligrams
(b) Randomly pick 42 fish from the entire pond and weigh each of them.
(a). Since we are interested in the masses of the fish and not the time
so that, only unit of mass is to be considered.
Therefore, Kilograms, grams and milligrams are used to find the average mass.
(b). Since, Random sampling is a part of the sampling technique in which each sample has an equal probability of being chosen
Therefore, Randomly pick 42 fish from the entire pond and measure their masses. This will provide a representative sample with no bias.

A rectangle's length is 4 more than twice its width. Its
area is 240 square centimeters.
Complete the work to find the dimensions of the
rectangle.
w(2w + 4) = 240
2w2 + 4w = 240
2w2 + 4w - 240 = 0
2(w + 12)(w - 10) = 0
What is the width of the rectangle?
2w + 4 A = 240 cm2
What is the length of the rectangle?
w
Answer:
Step-by-step explanation:
width = w
Length = 2w + 4
Area = 240 sq. cm
length * width = 240
(2w + 4) * w = 240
2w *w + 4*w = 240
2w² + 4w = 240
2w² + 4w -240 = 0
2(w²+2w - 120) = 0
2(w² + 12w - 10w - 10*12)=0
2 (w[w + 12] - 10[w + 12] ) = 0
2 (w + 12) (w-10) = 0
Ignore (w + 12) because measurement wont be in negative value
w - 10 = 0
w = 10
Width = 10 cm
length = 2w + 4 = 2*10 + 4 = 20 + 4
Length = 24 cm
Answer:
Width = 10
Length = 24

To solve this equation we just need to expand the brackets and then rearrange the equation to have x on one side and the numbers on the other:
2(x + 5) - 7 = 3(x - 2)
2x + 10 - 7 = 3x - 6
