yards/costumes:16/(5/2) = X/(19/2)
Cross multiply.
(5/2)x = 152
Multiply both sides by 2/5.
x = 101 1/3 yards
To make an equation that solves for the height as according to the volume of a pyramid, you must isolate the variable h on one side.
The first thing you have to do is to multiply both sides by 3 to get 3V=Bh.
Then, divide both sides by B to get your answer as h=3V/B.

Answer:
w = 2
Step-by-step explanation:
2(4w - 1) = -10(w - 3) + 4
8w - 2 = -10w + 30 + 4
8w - 2 = -10w + 34
+10w +10w
18w - 2 = 34
+2 +2
<u>18w</u> = <u>36</u>
18 18
w = 2
Answer:
y = 5x - 7
Step-by-step explanation:
Using the equation of a line with two points
y_2 - y_1 / x_2 - x_1 = y - y_1 / x - x_1
Giving two points
( -4 , 10)(16 , -2)
x_1 = -4
y_1 = 10
x_2 = 16
y_2 = -2
Using the above formula
y_2 - y_1 / x_2 - x_1 = y - y_1 / x - x_1
-12 - 3 / -1 - 2 = y - 3 / x - 2
-15/-3 = y - 3 /x - 2
Cross multiply
-15(x - 2) = -3(y - 3)
-15x + 30 = -3y + 9
-15x + 30 + 3y - 9 = 0
-15x +30 - 9 + 3y = 0
-15x + 21 + 3y = 0
3y = 15x - 21 ( following y = mx + C
Dividing through by 3 to find y
3y/3 = 15x -21 / 3
y = 15x - 21 / 3
We can still separate
y = 15x / 3 - 21/3
y = 5x - 7
Therefore, the equation of the line is
y = 5x - 7
