I believe the first answer is correct
My guess would be guess A
Answer:
x = 12
Step-by-step explanation:
Equation: 0.52(x) + 0.72(4) = 0.57(x + 4)
0.52(x) + 0.72(4) = 0.57(x + 4)
Multiply
0.52x + 2.88 = 0.57x + 2.28
Subtract 0.52x from both sides
2.88 = 0.05x + 2.28
Subtract 2.28 from both sides
0.6 = 0.05x
Divide all sides by 0.05
x = 12

20.75 because if you add 4.85+7.95+7.95 add that you get 20.75
(x+6)2 = x - 8
