• d ≤ 200

• d >200

• d ≤ 500

Use the number line to solve 4x > 20

My solution for x is: ​ (a)  

My graphed dot will be ​ (b)  

My arrow that I shade to include all the values of x will go ​ (c)  

​

• x > 5
• open
• right
• left
• closed/colored in

Answer explanation

4 x > 20

Divide both sides by 4 to get x by itself.

x > 5

now you can graph the dot and shade.

x can be who and still be greater than 5?
