When 14 is substituted for b, the number sentence is true.
Use an equation to determine the missing angle, labeled x in the diagram shown by your teacher.
x + 57 = 90
x + 57 - 57 = 90 - 57
x = 33
The measure of the unknown angle is 33 degrees.
Write an inequality statement for the following situation. Let X represent weight.
At the new festival, the rides have a weight limit. The maximum weight allowed is 2,000 pounds.
0 ≤ X ≤ 2,000
When labeling a graph, on which axis does the independent variable fall?
The independent variable is on the x-axis.
Jenna and Allie work together at a piano factory. They were both hired on January 3, but Jenna was hired in 2005, and Allie was hired in 2009.
If both workers continue working at the piano factory, when Allie has A years of experience on the job, how many years of experience will Jenna have on the job?

A beam of light is reflected off a mirror. You will be shown a diagram of the reflected beam. Determine the missing angle measure.
55 + x + 55 = 180
110 + x = 180
110 - 110 + x = 180 -110
x = 70
The missing angle measure is 70 degrees.

Create an equation.
A taxicab service charges a flat fee of $8.00 plus an additional $1.50 per mile. Show the relationship between the total cost (c) and the number of miles driven (m).
c = 1.50m + 8
Using the following equations, which movie streaming program would be the better buy if you plan on streaming 10 movies? Let "m" be amount of movies and "c" be total cost.
Stream System: c = 10 + .50m
Movie Madness: c = 13 + .25m
Stream system is the better option if you are streaming 10 movies.
Stream System: c = 10 + .50(10)
c = 15
Movie Madness: c = 13 + .25(10)
c = 15.50
On a number line, would I shade in the circle for the following inequality signs? < and >
No, you would not shade in the circle. You would leave it open.
Write the expression for the situation described below. Let "W" represent the week number.
Patrice is saving her money to buy a new laptop, which costs $1,000. She already has 500 dollars. If she earns $100 dollars per week, how many weeks will it take for her to earn $1,000.
500 + 100w
Alyssa is twice as old as Brittany, and Jazmyn is 15 years older than Alyssa. If Jazmyn is 35 years old, how old is Brittany?

When creating a graph, what are the five essential components?
Title, y-axis, x-axis, scaling of the x-axis and scaling of the y-axis
Using the following equations, which movie streaming program would be the better buy if you plan on streaming 50 movies? Let "m" be amount of movies and "c" be total cost.
Stream System: c = 10 + .50m
Movie Madness: c = 13 + .25m
Movie Madness has the better deal if you watch 50 movies.
Stream system 10 + .50(50) = 35.00
Movie madness 13 + .25(50) = 25.50
