Linear equations (one variable)

For a field trip 7 students rode in cars and the rest filled four buses.  How many students were in each bus if 203 students were on the trip?

• 56
• 50.75
• 49
• 43

Solve for x

Just write the number of the solution!!

7.3y − 5.18 = −51.9

• y = 5
• y = -6
• y = -10
• y = 0

When solving equations, my ultimate goal is to ________ the variable.

• multiply
• divide
• integrate
• isolate

Solve the equation below for the variable shown:

 $\frac{x}{8}+11=13$ 

•  $x=\frac{1}{4}$ 

•  $x=3$ 

•  $x=13$ 

• $x=16$

 $\frac{x}{5}-13=20$  

•  $x=145$  

•  $x=165$  

•  $x=180$  

•  $x=190$  

-11 + y/5 = -7

• 4
• -24
• -90
• 20

• 21

• 49

• 6

What does the variable represent in the following problem?

A handyman charges a flat rate of $70 and an additional $30 per hour for labor. How many hours did the handyman work if he made $250?

• money

• handymen

• hours

• labor

10x+5=25

• x=1

• x=2

• x=5

• x=10
