10.50/5=2.10
2.10*4=8.40
She used to earn $8.50/hr
Since there is two negative signs in the original equation, you need two negative signs in the equivalent one as well.
Because one of the negatives if before the fraction, it doesn't matter if the second negative is on the 13 or on the 12.
The answer is A.
Answer:

Step-by-step explanation:
To solve this proportion, we will divide the two given denominators.
Now, we have: 30 ÷ 5 = 6
Next, we will multiply the given numerator by the quotient: 3 × 6 = 18
So, our final proportion will have to be:

One way is factor
exg
if you wanted to find the square root of 36 you would factor
36=2 times 2 times 3 times 3
then group repeeting numbers then write only one of them
36=(2 times 2) times (3 times 3)
squareroot36=2 times 3=6
so factor 65
65=5 times 13
that doesn't help
next step
find squares close to that numbers
1^2=1
2^2=4
3^2=9
4^2=16
5^2=25
6^2=36
7^2=49
8^2=64
9^2=81
the answer is a little more than 8
the more exact one would be from a calculator (8.0622577482985)
