Which expression is equivalent to 20c - 8d?

• 2(10c + 4d)

• 4(5c - 8d)

• 4(5c - 2d)

• c(20 - 8d)

2(c - 8)

• 2c - 16
• 2c + 16
• 2c - 8

Which equation has x = 5 as the solution?

• x + 15 = 10
• 2x = 5
• 2x = 10

What is the correct step to solve for the variable?
15 = m - 5

• add 15 to both sides
• add 5 to both sides
• subtract 15 from both sides
• subtract 5 from both sides
