Creating Equations and Inequalities

There were 331 students that went on a field trip. Six buses were filled and 7 students traveled in a van. How many students were on each bus?

• 6 + 7x = 331

• 331 - 6x = 7

• 6x + 7 = 331

• 6x + 7y =331

A computer printer can print 10 pages per minute. There were already 35 pages in the tray.The total pages printed was 115 pages. How many minutes has the printer been running?

• 35 + 10x = 115

• 35x + 10 = 155

• 155 = 10 + 35

• 155 + 10x = 35

5x < 5

• x < 1

• x > 1

• x > 0

• x < 25

Pick the correct inequality.

• A

• B

• C

• D

WRITE AN EQUATION
For a field trip 4 students rode in cars and the rest filled nine buses. How many students were in each bus if 472 students were on the trip?

• 4x=472

• 9x=472

• 4+9x=472

• 4+x=472

When graphing an inequality, you use an open dot when you use which symbol?

• <, >

• ≤, ≥ 

The product of 12 and a number is the same as 2 removed from a number

• 12x=x+2

• 12x=2-x

• 12-2=x-2

• 12x= x-2

a number halved is equal to 22 fewer than a number

• b⁄2 = 22-b

• 2b =22- b

• n⁄2=n-22

• None of the above

The 30 members of a choir are trying to raise at least $1500 to cover travel costs to a signing camp. They have already raised $600. Which inequality would you solve to find the average amount each member can raise in order to meet the goal?

• 30x + 600  ≥ 1500

• 30x + 600  ≤ 1500

• 30x  - 600  ≤ 1500

• 30x = 1500

The room holds no more than 400 people. Which inequality represents the amount of people the room holds?

• P ≥ 400

• P ≤ 400

• P < 400

• P > 400
