How would you solve this equation for x?

4x = 36

• subtract 4 from both sides

• divide both sides by 36

• divide both sides by 4

• multiply both sides by 4

Wyatt solves the inequality 2y + 2 < 10 for y and gets y < 5

He plugs 5 in for y to check his solution. Was he correct?

• Yes. 2(5) + 2 < 10 means 10+ 2 < 10

  so 12 < 10 makes sense

• No. 2(5) + 2 < 10 means 10+ 2 < 10

  so he gets 12 < 10 which is not true

• No. It should have been y > 5

• m = 10 - (3.50 + 2.75)

• m = 10 + 3.50 + 2.75
