I already know the answers but I need someone to help/show me what it looks like solved on a number line

[see below]

Step-by-step explanation:

3 * (-5) = -15

Locate the '-15' line and plot a closed circle on it.

-2 * -3 = 6

Locate the '6' line and plot a closed circle on it.

Hope this helps.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
