Answer:
Each bag costs $4.75
Step-by-step explanation:
41.22 = 3.22 + 8x
38 = 8x
4.75 = x
N = 13/20 or 0.65
25.5n - 3 = 5.5n + 10
Add 3 to both sides of the equation.
25.5n = 5.5n + 13
Subtract 5.5n from both sides.
20n = 13
Divide both sides by 20.
n = 13/20 or 0.65
The cube has 6 this same faces.
Therefore the surface area is equal 6 · 7cm² = 42cm²
Y= k/x
When y=42, x=6
42= k/6
k= 42x6
=252
When x=9,
y= 252/9
= 28
