Write what you know in an equation: 27=30%•X. Divide 27 by .30 to get X alone: 27/.30=90. 27 is 30% of 90 :)
Hello!
First you have to find out how many hours she works
She worked 8 hours a day for 5 days
8 * 5 = 40

The answer is $18 an hour
Hope this helps!
Answer: -9 and 7
explanation:
-9+7=-2
-9x7=-63
In this question there is 1 equation with 1 unknown variable. So it is absolutely possible to find the value of the unknown variable "x".
(4x - 1)/3 = 7/1
4x -1 = 7 * 3
4x - 1 = 21
4x = 21 + 1
4x = 22
x = 22/4
= 11/2
So the value of the unknown variable x is 11/2. So the correct option is option "d". Hope i have answered your question correctly and helped you to understand the method by which these problems should be done.
