7th Math Unit 3 Day 12 - 2/9

Solve--Use inverse operations to solve the inequality (get the variable by itself).

x+3>15

List out three solutions to the inequality.

Reverse??--Start with the given inequality, then divide both sides by -2.

Type out your new inequality.

-10<6

Solve 2--Solve the given inequality. Type your solution set to the inequality.

Ex) x > 4

-\frac{1}{3}x>7

Solve--Use inverse operations to solve the inequality (get the variable by itself like we do for equations).

x-7<18

List out three solutions to the inequality.

Negatives again--Use inverse operations to solve the inequality (get the variable by itself).

-4x>24

List out three solutions to the inequality.

True or False?--Is 7 a solution to the inequality x≤-9 ? Explain why or why not.

"I think 7 (is / is not) a solution because..."

SPICY-

Solve the two-step inequality.

7x+3>45

List out three possible values of x.

Solve the inequality

–2x + 5 < 13

Solve the inequality

3x + 4 > –11

Solve the inequality

–4x + 7 < 27

Solve the inequality

5x – 3 > 22

Solve the inequality

–2x + 9 < 19

Solve the inequality

3x – 6 > –15

Preserved or Reversed?--Solve the inequality.

-9x<90

List out 3 possible solutions.

CFS:

#1: Accurately solves inequality with inverse operations

#2: Accurately interprets solutions

Read and analyze the problem and solution.

2x + 5 < 55

Step 1: Subtract 5 from both sides 2x < 50

Step 2: Divide both sides by 2. x < 20

Is the solution x < 20 Correct? Explain why or why not. If not, find the accurate solution.
