Answer:
Your answer is 3x = 15
Step-by-step explanation:
3x = 15
Since 3 is being multiplied by x, we divide both sides by 3. 3x/3 cancels out, and you're left with x.
15/3 = 5
x = 5
This is my take using algebraic methods.
From the given volume, we know that the ratio is:
![\text {Ratio of yellow eraser to white eraser = } \sqrt[3]{ \dfrac{16}{2} }](https://tex.z-dn.net/?f=%5Ctext%20%7BRatio%20of%20yellow%20eraser%20to%20white%20eraser%20%3D%20%7D%20%20%5Csqrt%5B3%5D%7B%20%5Cdfrac%7B16%7D%7B2%7D%20%7D%20)
From the given area, we know that the ratio is:
Equate the two ratio and solve for x:
![\sqrt[3]{ \dfrac{16}{2} } = \sqrt{ \dfrac{52}{x} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%20%5Cdfrac%7B16%7D%7B2%7D%20%7D%20%20%3D%20%5Csqrt%7B%20%5Cdfrac%7B52%7D%7Bx%7D%20%7D%20)
Cube both sides:
Square both sides:
Simplify each term:
Cross multiply:
Divide both sides by 256:
Cube root both sides:
Answer:
a ) x = - 3, y = 5
x = 0, y = 2
x = 5, y = - 3
b ) you should draw the line by marking the coordinates in the graph, then draw a straight line passing through all those three points.
Step-by-step explanation:
y = 2 - x
When x = - 3,
y = 2 - x
= 2 - ( - 3 )
= 2 + 5
y = 7
When x = 0,
y = 2 - x
= 2 - 0
y = 2
When x = 5,
y = 2 - x
= 2 - 5
y = - 3
b ) you should draw the line by marking the coordinates in the graph, then draw a straight line passing through all those three points.
