Solve: .5x + 8 ≤ 10 What is x equal to?

x ≤ 2/5

Step-by-step explanation:

Step 1:  Subtract 8 from both sides

5x + 8 - 8 ≤ 10 - 8

5x ≤ 2

Step 2:  Divide both sides by 5

5x / 5 ≤ 2 / 5

x ≤ 2/5

 x ≤ 2/5

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
