What does 2/3 + 1/3 + 5/3 =?

8/3

Step-by-step explanation:

Since all of them have like denominators we should just add

 =

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
