You would take 175 divided by 5 which is 35 so 35 pages
Domain is x and range is y
Surface area is taking the area of each face and adding it together. The equation is 2lw + 2hw + 2hl. So, for example, you'd take the length and the width to the find the area of the top. Multiply this by 2 to find the top AND the bottom. You need to end with 6 sides and all these together to find your surface area.
Unit rate = 3/8 : 1/6
We can also write this as:
3/8 / 1/6
Flip the 2nd fraction and multiply:
3/8 * 6/1
Multiply the numerators and denominators together:
18/8
Simplify by dividing the numerator and denominaotr by 2:
18 / 2 = 9
8 / 2 = 4
So we have:
9/4

The constant of proportionality,m, is 3 (option B)
