9. In the figure below the measure of angle x is 20° less than the measure of angle y. What is the measure of
angle y?

a

Step-by-step explanation:

the line is straight on the bottem so we can assume its 180 degrees so the equation i used to solve was (angle y)65 + (angle x)45(since angle x is 20 degrees less than angle y) + 70 = 180

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 : )
