Multiple Choice

Shaan bought a video game console and some games for $350. The video game console cost $200. Each game cost $25. Write an equation that represents how many games Shaan purchased.

• 350 + 25x = 200

• 200 + 25x = 350

• 200 + 25x > 350

• 200x + 25 = 350

Multiple Choice

Which of the following is the solution to the equation: 2x - 14 = 6

• -4

• 10

• 12

• 20

Multiple Choice

What's the difference between an equation and inequality?

• Equations have $$<>\le\ge$$ . Inequalities have $$=$$ .

• Equations have $$=$$ . Inequalities have $$<>\le\ge$$ .

​Graphing Inequalities

Match

Match each statement with the correct numberline.

y < 6

y > 6

y ≤ 6

y ≥ 6

• y < 6

• y > 6

• y ≤ 6

• y ≥ 6

Multiple Choice

Karis has $900 in the bank. Every time she rides the bus she spends $2. Write an inequality that Karis can use to see how many time she can ride the bus and still have more than $500 in the bank.

• 900 + 2x < 500

• 900 + 2x > 500

• 900 - 2x > 500

• 900 - 2x < 900

Exact same process as Equations

​

Only Difference:

If you multiply or divide by negative number you must FLIP the Inequalitiy SYMBOL​

--> Negative Numbers in front of the variable do this.​

​

Two Step Inequalities

Multiple Choice

Solve the inequality.

• $$x\ <-5$$

• $$x\ <5$$

• $$x>-5$$

• $$x>5$$
