Total squares= 12
1x + 2x = 12
3x = 12
3x/3 = 12/3
x = 4
1x4 = 4
2x4 = 8
So. C is the answer
Answer:
8x+12y+32
Step-by-step explanation:

Step-by-step explanation:
let : the pair of jeans = X
a. the equation is :
4(X-3) + 8 = 92
b. 4(X-3) = 92-8
4X -12 = 84
4X = 84+12
4X = 96
X = 96/4
X = 24
so, the price of each pair of jeans = $24
_________
For the solution x = 2.6, the left side of equation
(2x - 6) => would be 2(2.6)-6 = 5.2-6 = -8 ( the negative value),
but on the right side of the equation 4x+8 => 4(2.6) +8 = 18.4 ( the positive value)
this difference indicates that x=2.6 is not the right solution.
