Raul has $460 in his checking account. Each month, $45 is automatically deducted from his account to pay for his cell phone plan
olasank [31]

Answer:

7 Months

Step-by-step explanation:

x=number of months

how much is deducted total=number of months times amount deducted per m onth

amount deducted per month=45

number of months=x

how much deducted total=45x

460-45x>100

solve for x

add 45x to both sides

460>100+45x

subtract 100

360>45x

divide both sides by 45

7. 2+ 32 = 5+ 3z
SVETLANKA909090 [29]

Answer:

z=9\frac{2}{3}

Step-by-step explanation:

2 + 32 = 5 + 3z

34 = 5 + 3z

3z + 5 = 34

3z + 5 - 5 = 34 - 5

3z = 29

3z ÷ 3 = 29 ÷ 3

z=9\frac{2}{3}
