Translating that problem into an equation with x as a variable we get 3x + x +10 = 22. Combine like terms to get 4x + 10 = 22. Subtract 10 on both sides to get 4x = 12. Divide by 4 on both sides to get x = 3.
Now to plug in. The first number was represented by 3x. So substituting 3 for the x we get 3(3) = 9. And again for the second number represented by x+10, 3+10 = 13.
Your numbers are 9 and 13. To check just add them together. 13 + 9 is 22, I'll save ya the effort.
The answer to number one is A
You would do 3x+90=180 because a straight line equals 180°. then you find x=30. then x and z add to get 180 because x fits in the slot above z so 180-30 equals 150°. if z equals 150° then 180-150 equals 30. so x=30,y=15, and z=150
