Answer: 6
Step-by-step explanation:
Let use the subsitution method . Look at 11=x+y let get y on the side by itself. 11=x+y 11-x=y Then we are going to subsitute 11-x for y in the top equation so it look like 20.00=2.50x+1.00(11-x). 20.00 =2.50x+11-x. Let simplify and we get 1.50x+11=20. Subtract 11 from both sides we get 1.50x=9. Divide 1.5 by 9 and we get x= 6.
Answer:
x=45
Step-by-step explanation:
The angles are supplementary
45+3x=180
-45
3x=135
divide by 3
x=45
