answer: 60
age difference is 30 years
10x4=40
40-10=30
when she is 30 he will be 60 because 30(her age) + 30 (age difference) = 60
Answer: The rational expression that is needed is z^5/8.
In the problem, we are starting with 4z^5/7 and multiply by something. Then, we have z^10/14.
First, let's deal with the variables. We go from z^5 to z^10, so we had to multiply by z^5.
Second, our fraction went from 4/7 to 1/14, the missing factor would be 1/8 because 4/7 times 1/8 equals 1/14.
Answer:
103.
Step-by-step explanation:
If you plug in 9 for the value of x in the equation, 103 is your answer.
Yes because 2 is less than 4 and you would have to regroup
