Answer:
x =42.5
x+8 =50.5
3x+2 = 129.5
Step-by-step explanation:
The two angles shown are supplementary, so they add to 180
x+8 + 3x+2 = 180
Combine like terms
4x+10 = 180
Subtract 10
4x = 170
Divide by 4
x =42.5
x+8 = 42.5+8 = 50.5
3x+2 = 3*42.5 +2 = 127.5 +2 = 129.5

Answer:

Step-by-step explanation:
move the variable to the right(-2x) and change the sign(2x now) -3y=-12+2x then change the signs (-3y is 3y , -12 is 12 and then 2x becomes -2x again) then divide both sides of the equation by 3 so 12÷3=4 and -2x÷3=
then you're going to use the commutative property to reorder the terms . so your answer is 
Step-by-step explanation:
The no. won before=370
Total games played=500
No.of games played after=x
Total games won=x(since no games were lost)
Total games won=370+x
Total games played=500+x
Total percentage of win=75%
therefore
370+x/500+x=75/100
37000+100x=37500+75x
100x-75x=37500-37000
25x=500
x=20
therefore total match played after 500 matches=20
