Answer:
100.00
Step-by-step explanation:
x=number of months until the costs are the same
50 + 20x = 25 + 30x
25 = 10x
x = 2.5 months
50 + 2.5(20) =$100.00
9 has factors of 3*3.
2 is prime, so no factors.
from those two denominators, we can get the LCD of hmmm simply their product, namely 18.

now, recall that, to get the mixed fraction, we divide 89 ÷ 18, the quotient goes up front, the "4", and the remainder is the one atop, the "17".
Hi there! The answer is 10.

We can use PEMDAS (Parenthesis, exponents, multiply, divide, add, subtract) to find our answer.
Since we cannot work inside the parenthesis in this question and since we don't have exponents, we can move on to multiplying.

Our next step would be subtracting. To make the process of subtracting some easier, I'll first change the fraction into a decimal.

Finally subtract.

The answer is 10.
