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

Answer:
9.6667
Step-by-step explanation:
3t=29
Divide each side by 3
3t/3 = 29/3
t = 29/3
Three goes into 29 nine times (3*9 = 27 ) with 2 left over
t = 9 2/3
We know 1/3 = .3 repeating
so 2/3 = .6 repeating
t = 9 .6 repeating
The correct answer is B.)
