Answer:
y = 2
Step-by-step explanation:
y varies inversely with x setup is:
y = k/x
7 = (find 'k')
k = 7/1 · 2/3
k = 14/3
use what you know about 'k' and 'x' to solve for 'y'
y = 14/3 ÷ 7/3 (remember to multiply by the reciprocal when dividing fractions)
y = 14/3 · 3/7
y = 2
so for question 2 find the area of the rectangle first:
then you find the area of the triangles:
Add up all the answers:
and for question 3, part A, you just find the area of the 2 boxes and multiply:
so the surface area of the box is 90 square inches therefore the paint covered 90 square inches. For part B, just add up the length of the thick black lines:
