Answer:
B. 16
Step-by-step explanation:
Solve for s:
4(2s - 1) = 7s + 12
Expand out terms of the left hand side:
8s - 4 = 7s + 12
Subtract 7 s from both sides:
(8s - 7s) - 4 = (7s - 7s) + 12
8s - 7s = s:
s - 4 = (7s - 7s) + 12
7s - 7s = 0:
s - 4 = 12
Add 4 to both sides:
s + (4 - 4) = 4 + 12
4 - 4 = 0:
s = 12 + 4
12 + 4 = 16:
s = 16
B) 16
8s-4=7s+12
s-4=12
s=16
I think type answer is A
3000
640x3 = 1920
90x12 = 1080
