Answer:
$9
Step-by-step explanation:
The artist buys 8 brushes that cost $5 each, then all brushes cost
He pays $94 for all brushes and cans of paint, then all cans of paint cost
If he buys 6 cans of paint, then one can of paint costs
x = 9
50+80+(6x-4)=180 (ANGLE SUM PROPERTY)
130 +(6x-4)=180
6x-4=180-130
6x-4=50
6x=50+4
x=54/6
x= 1 :))
I think C would be for number 11
A is for 12.
x/2 < - 18
