Answer:

x = -3

Step-by-step explanation:

first, take out the x on the right side and move it to the left side (subtract the 13x from 13x and subtract 13x from -2x). then amove 23 from the left side to the right side (add 23 to 23 and add 23 to 22). the equation should be -15x = 45 now. divide -15 from both sides and you should get x = -3!

Paul has $145 in his savings account. He earns $36 a week mowing lawns. If Paul saves all of his earnings, after how many weeks

Lemur [1.5K]

Answer:

Paul will have no more than $ 450 in next 8 weeks.

Step-by-step explanation:

From the information given on statement, we know that Paul saves all of his earnings weekly. Then, the money save is equal to the sum of initial amount ( $C_{o}$ ), measured in monetary units, and week earning ( $R$ ), measured in monetary units, multiplied by a number of weeks ( $n$ ), dimensionless:

$C =C_{o} + n\cdot R$ (1)

Now we clear the number of weeks within the formula:

$n = \frac{C-C_{o}}{R}$

If we know that $C_{o} = \$\,145$ , $C = \$\,450$ and $R = \$\,36$ , then the number of weeks is:

$n = \frac{\$\,450-\$\,145}{\$\,36}$

$n = 8.472$

Paul will have no more than $ 450 in next 8 weeks.
