Eddi Din [679]3 years ago

3x-13=2

move -13 to the other side

sign changes from -13 to +13

3x-13+13=2+13

3x=2+13

3x=15

divide both sides by 3 to get x by itself

3x/3=15/3

cross out 3 and 3, divide by 3 and then becomes 1*1*x=x

x=15/3

x=5

answer:

x=5

Which inequality has a closed circle when it is graphed on a number line?
marissa [1.9K]

Answer:

D

Step-by-step explanation:

The line underneath the greater than sign indicates that x is greater than or equal to 3, meaning x could be 3, 4, 5, etc. Therefore, if you were to graph this, you would have a closed circle on 3 because a closed circle indicates that x could be the number 3 or anything greater than 3.
