1. Regina typically runs at a rate of 5.6 miles per hour. If she ran at this rate for 72 minutes, how
far did she run? Use the distance formula shown below.
d = rt
A. 67.2 mi
B. 4.7 mi
C. 6.72 mi
D. 403.2 mi
2. If money is invested for a short period of time, simple interest is paid using the following
formula.
I = Prt
P is the money invested, or principal amount, r is the simple interest rate, and t is the time, in
years, the money is invested.
Given P = $2,500, r = 8%, and I = $1,800, how long was the money invested?
A. 8 years
B. 9 years
C. 10 years
D. 0.09 years
3. Which step should be used to find the value of t?
t - 23.4 = 53.6
A. subtract 23.4 from both sides
B. divide both sides by 23.4
C. add 23.4 to both sides
D. multiply both sides by 23.4
4. Which step should be used to find the value of w?
w + 56 = 90
A. add 56 to both sides
B. subtract 56 from both sides
C. multiply both sides by 56
D. divide both sides by 56

A. 23.6 g/cm3
B. 3 g/cm3
C. 0.33 g/cm3
D. 2.8 g/cm3
7. Mrs. Sharp drew this model.
Which equation does this model represent?
A. 4x - 3 = 10
B. 3x - 4 = 10
C. 4x + 3 = 10

A.
B.
C.
D.
9. Which of the following statements describes a correct method for solving the equation below?
15 + 3x = 18
A. Divide both sides of the equation by 3, and then add 15 to both sides.
B. Divide both sides of the equation by 3, and then subtract 30 from both sides.
C. Add 15 to both sides of the equation, and then divide both sides by 3.
D. Subtract 15 from both sides of the equation, and then divide both sides by 3.
