Instructions

This is a case sensitive test. Please be careful that you are capitalizing variables that need to be. 
For inequality questions please use >= to represent greater than or equal to or <= to represent less than or equal to.
When typing in answers for literal equations, be sure to use parentheses to show the correct order of operations 
ex. 3-4/2 is not the same as (3-4)/2

Which statement below is true?
6(x - 3) = 30
6x - 18 = 30
6x = 12
x = 2

Solve the following inequality
-2(x - 3) + 7 < 12

Solve for b in the equation:
ax + by = d

Jalil is driving on the freeway. He just passed mile marker 200. The markers have been increasing as he drives by them. The fastest Willow will drive is 65 miles per hour. However there is a bit of traffic that might slow him down, but he doesn’t know exactly how much it will slow him down.

a. Write an inequality to represent Willow’s speed.

Write an inequality to represent Jalil's position relative to the mile markers two hours from now. Use x to represent speed.

Solve the literal equation for A.
(4/3)A + 3B = C

Solve the inequality given and select the correct solution:

You are mowing lawns to earn money to buy a new video game system, which costs $450. You plan to save every dollar you earn. In addition, you want to be able to afford the accessories for the video game system (e.g., controllers, games). You already have $120 You charge $12 per hour. Write an inequality to show how many hours you need to work before you have enough money to purchase the video game system and its accessories.
Use x to represent how many hours you've worked.

Rewrite this equation in slope-intercept form by solving for x:
4y+ 8x = 28

Oftentimes, people get confused about how to solve inequalities that involve negative values. What is the confusion that people have? Explain the rules for solving inequalities and explain why they are the way they are -- at least two sentences for full credit.
