Answer:
C
Step-by-step explanation:
2 times 10 is 20. 2 times x is 2x. 2 times -4 is -8. So that gives you 20+2x-8. Combine like terms, so you don't have anything that matches with 2x, so you leave that aside. So you subtract/add 20-8 which gives you 12 and add the 2x on that. So the full answer is 2x+12.
Answer: x=40 y=140
Step-by-step explanation:
To work out x:
The angles in a triangle always add up to 180.
You already have one angle which is 50 the bottom left angle is a right angle and right angles always equal 90. To work out x, do 50+90=140 then do 180-140=40.
To work out y:
Angles on a straight also add up to 180.
So as you have figured out what x is (40) you would take it away from 180 to give you y.
180-40=140
Hope this helps :)
