Jacob solved the following equation using the steps shown.

Step 1 5x + 9 = 2x - 3

Step 2 3x + 9 = -3

Step 3 3x = -12

Step 4 x = -4

What operation did he perform to get from Step 1 to Step 2?

Subtracted 2x from both sides of the equation

Subtracted 9 from both sides of the equation

Multiplied both sides of the equation by 3

Added -3 to both sides of the equation

10.

Solve for x:

2x - 5 = 3x + 4

x = 6

x = -9

x = -18/13

x = 10/3

Two seventh-grade classes are selling raffle tickets to raise money.
-One class is selling tickets for $3.50 each and has already raised $400.
-The other class is selling tickets for $2.00 each and has already raised $300.
Which equation can be used to find m, the number of tickets each class needs to sell so that the total amount raised is the same for both classes?

5.5m = 700

3.50m = 2m + 300

3.5m + 400 = 2m + 300

3.5 + 400m = 2 + 300m

Mona is ordering cups for her school. Company A charges $3.50 for each cup and a one-time starter fee of $14. Company B charges $0.50 for each trophy and a one-time starter fee of $22.
Which inequality can be used to find x, the minimum number of cups that can be ordereed so that the total charge at Company A is less than the total charge at Company B?

3.5x + 14 < 0.5x + 22

3.5x + 14 > 0.5x + 22

3.5 + 14x < 0.5 + 22x

3.5 + 14x > 0.5 + 22x

13.

The equation below represents the amount of fees charged by two companies.
20 + 1.20v = 5 + 4v
Which scenario best describes the fees charged when v represents the number of miles.

GO charges $1.20 per mile. MILA charges $4 per mile.

GO charges $20 per mile and a renting cost of $1.20. MILA charges $5 per mile and a $4 renting cost.

GO charges $1.20 per mile and a renting cost of $20. MILA charges $4 per mile and a $5 renting cost.

GO charges $1.20 per mile and a renting cost of $20. MILA charges $5 per mile and a $4 renting cost.

Plop has $50 and spends $3 every day. Flip has $4 and saves $3 every day. Which equation could be used to determine when they have the same amount of money?

50 + 3x = 4 - 3x

50 - 3x = 4 - 3x

50 + 3x = 4 + 3x

50 - 3x = 4 + 3x
