prior = 32.4 . . . . . . . subtract 8.1 from both sides

<em>Comment on the problem statement</em>
When you're talking about a percentage increase in a percentage, it is almost never clear whether you're talking about the percentage of the underlying number, or the percentage of the percentage.
Here, we assume the 8.1 is a percentage of working students, not a percentage of the percentage of workings students. If you actually intend the latter, the percentage before the increase was about 37.465%.
Answer:
x =50
Step-by-step explanation:
Distance/Speed = Time
Distance=1,071 Speed=63 Time=x
1,071/63 = x
17 = x
Answer:
X = 11
Step-by-step explanation:
So, in order to solve this equation, we need to isolate x.
So, we are going to subtract 8x from the right side to get the x on one side. The equation should look like this:
-2x + 7 = -15
Now in order to get x all alone on one side, we need to subtract 7 from the left side.
-2x = -22
Now we just have to divide the -2 from x.
X = 11
