What do you know so far?
It’s OK if you aren’t sure of the answers to these questions because soon you’ll watch a video about friends making a movie that will help you learn about linear equations with one variable.
Then after you do some practice problems, you’ll take another short quiz so you can compare how you did against where you started.
Start
1
Which approach will allow you to solve a linear equation with one variable?
a
Add the variable and its coefficient, then remove the equals sign
b
Graph the equation as a curve
c
Get the variable alone on one side of the equals sign with the other terms simplified into one number on the other side
d
Combine the coefficients into the equals sign

Liza earns $10 each morning running the ticket table for her friends’ first movie. After school, she crafts astronaut helmets for the costumes. She earns an extra $5 for every helmet she makes. Write an equation to determine how many astronaut helmets Liza needs to make each day to reach her daily earning goal of $70.
a
$70a + $5 = $10
b
$5a + $10 = $70
c
$10a + $5 = $70
d
$5a - $10 = $70
3
Solve Liza’s equation of $5a + $10 = $70 to determine the number of astronaut helmets she must create to meet her goal.
a
12
b
8
c
4
d
10

Student filmmakers Aly and Omar are raising money for their film. To figure out how much to charge to see their movie, they take different elements into account and set up the following: 10x + 10x - x - 2($20). How can they simplify this expression?
a
x - $40
b
10x - $18
c
19x - $40
d
21x - $40

It’s marketing time! Aly and Omar want to put up flashy flyers around town to advertise their movie. They pay a designer $40 to create the layout. At the local print shop, photocopying the flyers costs $0.11 per page, and laminating them to withstand outdoor weather costs $1.39 per page. Their flyer budget is $85. How many flyers can they produce if they both copy and laminate each one? Set up and solve the equation.
a
$0.11x + $1.39x + $40 = $85 | x = 83 flyers
b
$0.11 + $1.39 + $40x = $85 | x = 2 flyers
c
$40x + $0.11x + 1.35x = $85 | x = 2 flyers
d
$0.11x + $1.39x + $40 = $85 | x = 30 flyers
