Answer:

= −23

Step-by-step explanation:

Subtract the numbers

3 + 7 - 11-31 = 160

3-24 - 11 = 160

Combine like terms

3 - 24-11 = 160

-8 - 24 = 160

Add 24 to both sides of the equation

-8 - 24 = 160

-8 - 24 + 24 = 160 + 24

Simplify

Add the numbers

Add the numbers

--> -8 = 184

Divide both sides of the equation by the same term

-8 = 184

-8/-8 = 184/-8

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

--> = -23

A student deposits the same amount of money into her bank account each week. At the end of the second week she has $30 in her ac
Nonamiya [84]
The student will have $135 in her bank account at the end of the ninth week. You can fine this out by finding out the amount she deposits a week and to do this you would take the $30 and divide it by 2 because she had $30 at the end of the second week. 
30/2=15
So you see that the student deposits $15 each week, so to find out how much money she will have in 9 weeks you will multiply her $15 by 9.
15x9=135
So the student will have $135 at the end of the ninth week.
