She worked 30 hours per week.
The problem turns out to be the following:
2x+15=3x-15.
First you need to have only one x variable so you subtract the X's:
3x-2x=X
The problem now turns into 15=x-15.
You have to isolate the X so you do x+15. You have to do the same to the other side so 15+15=30, therefore x=30
4. -8
5. 24
6. I can't see it properly so if it's ÷ answer is 9 if it's - answer is -70
You would convert 500 inches to centimeters, which is 500 times 2.54= 1270, then divide that by 365 days, leaving you with an answer of 3.47945205479, or just 3.47 centimeters.
Answer:
Karen has only 2 checkers left
Step-by-step explanation:
Jasper has 7 checkers than Karen
Jasper has 9 checkers

It can also be written as
9 - 7 = k
k = 2
Therefore Karen has only 2 checkers left
