Answer:

  Dawn has $1670 in account 1 and $1570 in account 2.

Step-by-step explanation:

Dawn can multiply the second equation by 8 and add 7 times the first equation.

  8(3/8A +7/8B) +7(A -B) = 8(2000) +7(100)

  10A = 16,700

  A = 1670

  B = 1570 . . . . 100 less than A

Dawn has $1670 in account 1 and $1570 in account 2.

__

<em>Check</em>

  3/8(1670) +7/8(1570) = 626.25 +1373.75 = 2000

First do inside the parenthesis first.

When dividing two exponents subtract them.

15-5 = 10

So w^15 / w^5 becomes w^10


Now you have (w^10)^4

Now multiply the exponents:

10 x 4 = 40

Final answer is w^40
