Q: Solve. Check your solution.

0.4x + 3.9 = 5.78
- x = 4.7
- x = 24.2 (You need to subtract 3.9 or add -3.9 to both sides first.)
- x = 0.752 (Remember you undo multiplication by dividing.)
- x = -6.5 (Incorrect)
A: x = 4.7

Q: Solve. Check your solution.

- w = 1.25 (You need to add 3/4 to both sides first.)
- w = 2
- w = -2 (Careful about negative signs.)
- w = 3.75 (Incorrect.)
A: w = 2

Q: The trapezoidal prism below has a volume of 136 m^3.  Write an equation to find the missing edge length.

[Image: Missing base length of trapezoidal prism; other base 6 m, height of trapezoid 8 m, height of prism 2 m]
- 8(x + 6) / 2 * 2= 136 (Awesome!)
- 8(x + 6) / 2 = 136 (Don't forget about the height of the prism.)
- 8(6) / 2 + 2x = 136 (Remember that the volume of any prism is the area of the base times the height.)
- 8x / 2 * 2 = 136 (The area of a trapezoid is (base 1 + base 2)* height / 2)
A: 8(x + 6) / 2 * 2= 136

Q: In accordance with the Mountain Heights Academy Honor Code, I declare that the work on this test is my own work.

I may use a calculator for calculations, but I solved the equations myself.
- True
- False
A: True

Simplifying Expressions Vocabulary

variable - a variable is a letter that is used to represent an unknown quantity

algebraic expression - a combination of variables and numbers with operations that has no equals sign

term - a number or a variable, or a number and variable multiplied together.Terms in an expression are separated by add or subtract. In the expression 3x + 4y - 9, 3x, 4y, and 9 are the terms.

coefficient - the number multiplied to a variable. In the term -5x, -5 is the coefficient.

constant - a number that is not multiplied to a variable

like terms - terms that have the same variables

Write Inequalities from Sentences

When translating sentences into inequalities, look for the following key words:

Key words | Inequality symbol
at least no less than minimum | >
no more than at most maximum | <
more than | >
less than | <

Example:
John needs to make a salary of at least $30,000 a year. Write an inequality for his salary, s.
"At least" means $30,000 would be acceptable, but he could make more. Use greater than or equal to.
s > 30,000
