Describe the steps you would take to solve for the variable x in the following

Mathematics
1 answer:
adoni [48]3 years ago
5 0

Answer:

x =  19

Step-by-step explanation:

1. add 31 on both sides (you wanna get the "x" by itself)

ex: 2x - 31 = 7

          +31   +31

2. the 31s cancel each other out so now you add 31 + 7

2x       =  7

           +31

___________

             38

3. divide 2 on both sides so the 2s cancel each other out and only the x is left

ex: 2x / 2 = x         38 ( the 38 stands alone)

4. now divide 38/2 and you have your answer

X= 19

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.
