Unit 5 & 6 Review

Unit 5 & 6 Review

​This is your independent practice for our last math test that we will take IN CLASS on Thursday.

​Values from a Replacement Set

A replacement set is a list of choices.

It looks like this: {2, 3, 4, 5}

If it asks for a value, that means only one answer.

If it says which values, that means there is more than one answer.

Try each choice!

Multiple Choice

Which value from the replacement set is a solution to this inequality?

n + 8 $$\ge$$ 15

{4, 5, 6,7}

• 4

• 5

• 6

• 7

Multiple Select

Which values from the replacement set make up solutions for this inequality?

2n + 3 < 12

{3, 4, 5, 6}

• 3

• 4

• 5

• 6

​Solve Equations

To solve equations, isolate the variable. That means you want the variable to be on one side of the equation and everything else to be on the other side. To do this, you want to do the opposite (or inverse) operation to both sides. If you want to get rid of the +5, then you need -5 to both sides of the equation.
You can also write all the related equations and use the equation that isolates the variable.

Fill in the Blanks

N + 4.3 = 25

You want N to be by itself on the left, so how do you get rid of the +4.3?

Subtract

from both sides.

Fill in the Blanks

N + 4.3 = 25

Solve for n.

Fill in the Blanks

4n = 20.8

You want n by itself on the left. How do you get rid of the x4?

You divide by

on both sides.

Fill in the Blanks

4n = 20.8

Solve for n.
