Answer:
x=-7
Step-by-step explanation:
1/2x-3+5x/2x+6=2
1/2x-3+5/2+6=2
1/2x+3+2.5=2
1/2x+5.5-2=0
1/2x+3.5=0
0.5x=-3.5
x=-7
Hi,
5x - 5 + 3x + 3 = 2x - 2.
2x - 2 = 180°
So x = 180/2 - 2 = 88°

Answer:
10 games
Step-by-step explanation:
Let C be cost and x be number of games
Arcade A: C = 5 + 0.6x
Arcade B: C = 7 + 0.4x
for both arcades to be the same price, Both C's must be equal, hence we equate the right side of both equations:
5 + 0.6x = 7 + 0.4x (subtract 5 fromboth sides)
0.6x = 7 + 0.4x - 5
0.6x = 2 + 0.4x (subtract 0.4x from both sides)
0.6x - 0.4x = 2
0.2x = 2 (divide both sides by 0.2)
x = 2 / (0.2)
x = 10
