Answer:
X = 26
Step-by-step explanation:
So we know that a straight line equals 180º and we're given both equations. So you just have to set both equations equal to 180. It should look like:
2(x + 15) + (3x + 20) = 180
Use distributive property on the first equation
2(x + 15) = 2x + 30 so now your equation looks like 2x + 30 + 3x + 20 = 180
Add like terms
2x + 30 + 3x + 20 → 2x + 3x = 5x → 30 + 20 = 50
Your equation should look like
5x + 50 = 180
Subtract 50 from both sides, your goal now is to get x by itself
180 - 50 = 130
Divide both sides by 5. 130/5 = 26
X = 26
So now the equations added up should equal 180º. Just plug 26 in to x to solve.
2(26 + 15) + (3 x 26 + 20) = 180

have a lovely day <3
Answer:
C. -7y+8
Step-by-step explanation:
B because it’s really the answer
Well thinks of it as 10/10, so Cathy revived 1/5, so that means 3/10th then Zhong received 1/8 which is 2/10th. Stacy revived the average which it about 49% or 3/10. which can only mean Benny got 2/10!
