Question

Solve the inequalities. Show each solution as an interval on the number line.
5x+3≤21

Answer 1

x≤3.6

Explanation:

First, lets simplify the equation:

5x+3≤21

5x≤18

x≤18/5

x≤3.6

To draw this on the number line, draw a filled in circle 6/10 to the right of 3 and 4/10 to the left of 4. Then draw an arrow pointing to the left.

I hope this solution was useful. Happy mathing!

Answer 2

`x \leq (18)/(5)`, (Please see attachment)

Explanation:

`5x + 3 \leq 21`

`5x \leq 18`

`x \leq (18)/(5)`
