Solve Linear Equations and Inequalities

Kayla went golfing with $45. She rented the equipment she needed for $15, and she needs to know how many rounds she is able to afford with the leftover money. Each round costs $6. Write an inequality to solve for "r", the greatest number of rounds she can afford.

• 6r + 15 < 45

• 6r + 15 < 45

• 15r + 6 > 45

• 15r + 6 > 45

In order to watch a movie at the theater, you must purchase an $8 ticket. If snacks are $4 each, how many possible snacks could you purchase with $20? Use the inequality from the previous question and solve.

• less than 3 snacks

• at most 3 snacks

• at least 3 snacks

• more than 3 snacks

Solve:
6x+10>5x-12

• x>2

• x<2

• x<-22

• x>-22

What is the next step to solve this equation? 3x - 5 = 7

• Add 5 to both sides of the equation

• Add 3x to both sides of the equation

• Subtract 5 from both sides of the equation

• Subtract 7 from both sides of the equation

How do you solve 9x - 4 = 23

• divide both sides by 4, then add 9

• divide both sides by 9, then add 4

• add 4 to both sides, then divide both sides by 9

• add 4 to both sides, then divide by 23
