Answer: (I am not a maths moderator)
x=4
Step-by-step explanation:
Multiply the exponents
(2x-4)^12=(4^2)^6 (exponents multiply so)
(2x-4)^12=4^12
4^12 = 16777216
(2x-4)^12= 16777216
Take the 1/12 exponent for both sides
that will remove the ^12 exponent from the left side and will take the 12th root for the right.
2x-4=4
add 4 to both sides
2x=8
divide both sides by 2
x=4
Answer:
V= 8/3
Step-by-step explanation:
S = N + 4
N = H - 8
S = 15
S = N + 4
Plug in 15 for 'S':
15 = N + 4
11 = N
N = H - 8
11 = H - 8
Add 8 to both sides:
19 = H
So Hector receives $19 for allowance.
