Solve for x:
x + 8 = 2(0.5x + 4)
x + 8 = 2(0.5x + 4)
x + 8 = x + 8
8 = 8

What is the result of rotating a point (3, 2) 90 degrees counterclockwise around the origin?
(2 , -3)
300
Solve for x: 3(x-2) + 6 = 5(x+4)
3(x-2) + 6 = 5(x+4)
3x - 6 + 6 = 5x + 20
3x = 5x + 20
-2x = 10
x = -5

Jordan buys two new jerseys and a glove for softball. She pays $44 for the glove and gives the clerk two fifty-dollar bills to pay the exact amount. How much does Jordan pay for each jersey?
2x + 44 = 50 + 50
2x + 44 = 100
2x = 56
x = 28
$28 per jersey
