If you work 40 hours per week at $13.00 per hour and save 10% of your gross earnings, how much will you save per week?
Vesna [10]
You work 40 hours per week and make 13$ per hour, so multiply 40 and 13 and you get how much you make a week. Then find out what 10% of that number you got is and you get your answer.

You should get: 52$

7(3b-1)=2b-26 please help and give me step by step ☺️​
Colt1911 [192]

Answer:

b = -1

Step-by-step explanation:

7(3b-1): 7 goes into the numbers by multiplying. This will give you 21b-7.

So now the equation should be like 21b-7=2b-26.

-7 and 2b swap places, making 21b-2b=7-26. It will give you 19b= -19.

Finally divide the two numbers (-19 / 19) and the solution will be b= -1.

If I didn't make a clear answer or a good explanation, please comment. I sometimes mess up my steps, and this is my first time using this.
