There is more than one method that can be used to solve the following equation. Select all of the correct methods that you could use.

• Distribute 1/2 to the x and the 6, add 3, and then divide by 1/2 on both sides.

• Add 6 to both sides and then divide by 1/2 on both sides.

• Divide 1/2 on both sides and then add 6 to both sides.

• Multiply by 1/2 on both sides and then subtract 6 on both sides.

Solve for "d".

-4d - 8 > -14

• d > 3/2

• d < 14/4

• d < 3/2

• d > 8/4

Timothy bought a soda for $1.25 and candy bars for $0.30 each. If he spent a total of $2.15, which equation could he use to represent the situation?

• 1.25x + 0.30 = 2.15

• 0.30x + 1.25 = 2.15

• 2.15x + 0.30 = 1.25

• 0.30x + 2.15 = 1.25
