Question

Which represents the solution set of 5(x+5) < 85?

х< 12
x> 12
х< 16
х> 16

Answer 1

`\Huge \boxed{X<12}`

Explanation:

To solve this problem, first you have to isolate it on one side of the equation. Remember to solve this problem, find represents the solution of 5(x+5)<85.

First, you divide by 5 from both sides.

`\displaystyle (5(x+5))/(5)<(85)/(5)`

Solve.

`\displaystyle 85/5=17`

`\displaystyle x+5<17`

Next, subtract 5 from both sides.

`\displaystyle x+5-5<17-5`

Solve.

`\displaystyle 17-5=12`

As a result, the correct answer is x<12.

Hope this helps!

Have a wonderful blessing day! :)
