Expressions, Equations and Inequalities in Unit Six

Amanda rented a bike from Shawna's Bikes. They charged her $2 per hour, x, plus a $10 fee. Amanda paid less than $27. Which inequality represents this situation and what quantities are true for x?

• 2x+10≥27, where x≥8.5

• 2x+10<27, where x<8.5

• 2x+10≤27, where x≤8.5

• 2x+10>27, where x>8.5

Simplify by combining like terms:
5a + 2b - 3a + 4

• 8a + 2b + 4

• 2a + 2b + 4

• 8ab

• 4ab + 4

Simplify the expression:
8(5 + w)

• 40 + w

• 40+8w

• 85 + 8w

• 13+8w

(7a + 4) - (9a + 2)

• -2a + 6

• 2a + 6

• -2a + 2

• 2a + 2
