37.22 gallon or if you round up it would be 37 and 1/4
Answer: C) x = 2
2^{2x + 2} = 2^{3x}
Since both terms (above) have the same base, set the exponents to be equal:
2x + 2 = 3x (Rearrange to solve for x)
x = 2
∴ x = 2
Let w = washer and d = dryer:
w + d = $770,
but w = d + 70, replace w with d+70
(d+70) + d = 770
2d + 70 =770
2d = 770 -70 = 700
and d=$350, then w=350+70 = 420
1.981: One and nine hundred eighty-one thousandths
Yes they will be parallel. Now you try to solve it.
