The total value of the coins is 3.88. Anita has 4 more nickels than pennies and 2 more than 4 times the number of quarters than pennies. How many of which coins does she have?
Answer:
See explanations below
Step-by-step explanation:
Let the amount of nickel be x
Let the amount of pennies be y
Let the amount of quarters be z
If the the total value of the coins is 3.88, then;
x+y+z = 3.88 .... 1
If Anita has 4 more nickels than pennies, then;
x = y + 4 ... 2
If she has 2 more than 4 times the number of quarters than pennies, then;
y = 2 + 4z
4z = y-2
z = (y-2)/4 ...3
Substitute 2 and 3 into 1
y+4+y+(y-2)/4 = 3.88
4y+16+4y + y-2 = 15.52
9y + 14 = 15.52
9y = 15.52 - 14
9y = 1.52
y = 1.52/9
y = 0.17
Since x = y + 4
x = 0.17+4
x = 4.17
z = y-2/4
z = 0.17-2/4
z = -1.83/4
z = - 0.46

Solution
9 − − 8
Answer:
The answer is 9x - y - 8z.
Step-by-step explanation:
1) Expand by distributing terms.
[tex] - (8x + 6y) + 17x + 5y - 8z[/tex]
2) Remove parentheses.
[tex] - 8x + 6y + 17x + 5y - 8z[/tex]
3) Collect like terms.
[tex]( - 8x + 17x) + ( - 6y + 5y) - 8z[/tex]
4) Simplify.
[tex]9x - y - 8z[/tex]
Therefor, the answer is 9x - y - 8z.

Find the circumference of a circle with an area of 1809.56 square centimeters
Answer:
150.8cm
Step-by-step explanation:
Area= π r²
make r subject of the formula
A = π r²
A/π= πr² (dividing both sides by π)
r²= A/ π
r =
[tex] \sqrt{ \frac{a}{\pi} } [/tex]
r=√(1809.56)/(π)
r=√576.0008
r≈24cm
:. circumference= 2π r
= 2× π × 24
=150.7964
≈150.8cm

HELP ASAP. solve for x
Answer:
x = 25
Step-by-step explanation:
The triangle is isosceles, therefore, the base angles are the same
62 + 2x + 9 + 2x + 9 = 180
62 + 4x + 18 = 180
4x = 180 - 62 - 18
4x = 100
x = 100/4
x = 25

Quadrilateral:
We have 94° + 41° + a + b.
Using 111°, we can do 180 - 111 and get 69°.
Now, we have 94° + 41° + 69° + b.
A quadrilateral's angles will equal 360°.
94 + 41 + 69 + b = 360°
204 + b = 360°
b = 156
Triangle:
Now, we can do 180 - 156 to find x.
x = 24

What is the equation of a circle with the center (2,3) that passes through the point (5,3)
The given center and point on the circle of (2, 3), and (5, 3), respectively
gives the equation of the circle as; [tex]\underline{(x - 2)^2 + (y - 3)^2 = 3^2}[/tex].
How can the equation of the circle be found?The general form of the equation of the circle is presented as follows;
(x - h)² + (y - k)² = r²
Where;
(h, k) = The center of the circle
r = The radius of the circle
Which gives;
(h, k) = (2, 3)
h = 2
k = 3
r = √((5 - 2)² + (3 - 3)²) = 3
The equation of the circle is therefore;
[tex]\underline{(x - 2)^2 + (y - 3)^2 = 3^2}[/tex]Learn more about the equation of a circle here:

Complete question :
It takes 313131 employees and \$7500$7500dollar sign, 7500 to build a car, and it takes 191919 employees and \$4300$4300dollar sign, 4300 to build a motorcycle. Genghis Motors wants to spend more than \$84000$84000dollar sign, 84000 to build cars and motorbikes using at most 706706706 employees. Let CCC denote the number of cars they build and MMM the number of motorbikes they build. Write an inequality that represents the condition based on the number of employees. Write an inequality that represents the condition based on the number of dollars.
Answer:
31C + 19M ≤ 706
7500C + 4300M > 84000
Step-by-step explanation:
C = number of cars built
M = number of motorcycles built
Cost of building a car :
Cost = 31 + $7500
Cost of building a motorcycle,:
Cost = 19 + 4300
To build, C cars :
Number of employees = 31C
7500 * C = 7500C
To build, M motorcycles :
Number of employees = 19M
4300 * M = 4300M
Genghis budget :
Amount > 84000
Number of employees ≤ 706
Hence, the constraints
31C + 19M ≤ 706
7500C + 4300M > 84000

Find the slope of the line that contains the I
point (4, -9) and has a y intercept of 2.
Answer:
-11/4
Step-by-step explanation:
The y intercept has the coordinates of (0,2)
We have two points (0,2) and (4,-9) so we can find the slope using
m= (y2-y1)/(x2-x1)
= ( -9-2)/(4-0)
= -11/4
Answer:
-11/4
Step-by-step explanation:
y = mx + c
Point (x,y)
intercept c
slope m
-9 = m(4) + 2
-9 = 4m + 2
make m the subject of the formula
4m = -9-2
4m = -11
divide both sides by 4
m = -11/4
the point-slope for mhm of a line that has a slope of -2 and passes through point (5,-2) is shown below y+2=-2(x-5)
A. y=-2x+12
B. y=-2x+8
C. y=-2x-7
D. y=-2x-3
Answer:
y = -2x + 8 (B)
Step-by-step explanation:
Just expand y + 2 = -2(x-5)
y + 2 = -2x +10
y = -2x +8 (minus both sides by 2)
