**A. (10 points)
Circle T or F, whichever is correct.**

1.
**F** Two
equations are equal if they have the same solution sets.

2.
**T** 5,
rt, 3b, and d^{2}y are all terms.

3.
**F** Like terms are terms with exactly the
same variables and exactly the same coefficients.

4.
**T** The
formula which relates radius and circumference of a circle is C = 2pr.

5. **F** The formula for the volume of a
cylinder is V = 2prh.

6.
**F** The
symbol > means is less than.

7.
**T** A
solution of an inequality is any number which makes the inequality true.

8.
**F** The
inequality 3x < -6 is equivalent to x < 2.

9.
**T** The
equation 3x = -6 is equivalent to x = 2.

10.
**T** The
statement 3(h + 9) = 3h + 27 is an illustration of the distributive property.

**B. (10 points)
Fill in the blanks to correctly complete each statement.**

1.
The formula for the area of a circle with radius r is **A = ****pr2**.

2.
The formula that relates distance, rate, and time is **d = rt**.

**3. **The
formula which relates percent, percentage, and base is **percentage = (percent)(base)**

4.
If both sides of an inequality are multiplied by a **positive** real number, the resulting inequality
will be equivalent to the original inequality.

5.
If both sides of an inequality are multiplied by a **negative** real number and the sense of the
inequality is reversed, the resulting inequality will be equivalent to the
original inequality.

6.
If an expression is added to both sides of an inequality, the
resulting inequality will be **equivalent**
to the original inequality.

7.
To add like terms, add their **coefficients**
and keep the same variables with the same exponents.

8.
A **term** is a number or a
product of a number and one or more variables.

9.
**Percent** means parts per
one hundred.

10.
The product of a number and its **reciprocal**
is 1.

**C. (10 points) **

1. Is
3 a solution of the equation x^{3}
- 3x^{2} + x 3 = 1

**3 ^{3} 3(3^{2}) + 3 3 = 3^{3} 3^{3}
+ 3 3 = 0 **

2. When
solving the equation 4x = 16 do we divide both sides of the equation by 4 or do
we subtract 4 from both sides of the equation.
**Divide both sides of the equation by 4.**

3. Change
3.5% to a decimal **3.5% = 0.035**

4. Translate the following sentence into an equation. DO NOT SOLVE.

57 is 36.2% of what number?

**Use** **percentage =
(percent)(base) to obtain 57 = (.362)(base)**

5. Use
the distributive property to remove parenthesis from 3(k 2k^{3}) **= 3k 6k ^{3}**

**D. (30 points)
Perform the indicated operations.
**

1. Simplify
by combining like terms 3x + 5x 7x **= 8x 7x = x**

2. Simplify by combining like terms 12(m + 11) 11

** =
12m +(12)(11) 11 = 12m + 132 11 = 12m +121**

3. Evaluate
| y^{3} x | for y = -5 and x = -3

**|(-5) ^{3} (-3)| = |-125 + 3| = |-122| = 122**

**G. (10 points) **

A slice of pie with a scoop of ice cream has 850 calories. The calories in the pie alone are 100 more than twice the calories in the ice cream alone. How many calories are in each food?

**H. (10 points) **

The total area of the 50 states and the District of Columbia is 3,618,770 square miles. If Alaska covers 591,004 square miles, what percent is this of the U. S. total?

I want to see the equation and then I want to see the steps used to solve
the equation.

**Use** **percentage =
(percent)(base) to obtain 591004 = (percent)(3618770)**

Suppose a florist buys a dozen roses wholesale for $12.95 and sells them for $37.50.

Write an equation which relates the wholesale price, retail price, and markup in this situation.

IMPORTANT: I want the equation NOT
the solution.

** Use Retail price =
Wholesale price + markup to obtain**

**37.50 = 12.95 + markup**

**J. (5 points) **

The length of a
rectangular picture is 11.75 inches less than twice the width. The perimeter is 102.5 inches. What are the dimensions of the picture? I want to see the equation and then I want to see the steps used
to solve the equation.

**Let x be the width then the length is 2x 11.75 and the
perimeter is 2x + 2(2x 11.75) as well as 102.5.**

**This yields the equation
2x + 2(2x 11.75) = 102.5**

**2x + 4x 23.5 = 102.5**

**6x = 126**

**x = 21 is the width and the length is 2(21) 11.75 = 42
11.75 = 30.25**
