A mechanic wants to work a maximum of 10 hours tomorrow on tune-ups and oil changes. A tune-up takes 1 hour, and an oil change takes 2 hours. If x = the number of tune-ups and y = the number of oil changes Which inequality represents the situation?

Key Word: Maximum of = No more than

• x + 2y > 10

• x + 2y ≤ 10

• x + 2y ≥ 10

• x + 2y < 10

A formula to find the angle measures of an isosceles triangle is shown. 180 = 2x + y. Which equation can be used to find x?

To get x by itself, you need to subtract y, then divide by 2

• x = 90 + y

• x = (180 + y)/2

• x = 90 - y

• x = (180 - y)/2
