Assignment 1-1 Expressions and Formulas
Choice Strategy
Evaluate each expression.
10 + 16 ÷ 4 + 8
10 + 4 + 8 =
[21-(9-2)] ÷ 2
[21-( 7 ) ] ÷ 2
21-7= 14
14 ÷ 2 =
½ (52 + 3)
5 x 5
½ (25 + 3)
½ x 28 =
14(8-15) 2 14(8-15) 2 8-15 = -7 14 ( -7) =-98 -98 = -98 ÷ 2 = 2

Assignment 1-1 Expressions and Formulas
Choice Strategy
Evaluate each expression if a = 12, b = 0.5, c = -3, d = 1/3
6b – 5c 6 x 0.5= 3 5 x-3 = -15 3 - -15 =
C3 + ad
-3 x -3 x -3= -27 12 x 1/3 = 4
-27 + 4 =
9c + ab c
9 x -3 = -27 12 x .5 = 6
-27 + 6 = -27 +6
-27 + 6 = -21 ÷ -3 = -3
A) 15.3
B) 18
A) -23
B) 23
A) 7
B) -7

12 [ .5 2 (.5 + 12)]
12 [ .52 (12.5)]
.5 x .5 = .25
12 [ .25 x 12.5 ]
12 x 3.125 =
DISTANCE The formula to evaluate distance is d = r x t, where d is distance, r is rate, and t is time. How far can Tosha drive in 4 hours if she is driving at 65 miles per hour? d = r x t 65 x 4 = d = miles
