Assume that speed = 10 and miles = 5. What is the value of each of the
following expressions?
a. speed + 12 - miles * 2
b. speed + miles * 3
c. (speed + miles) * 3
d. speed + speed * miles + miles
10.
O
e. (10 – speed) + miles / miles

a. speed + 12 - miles * 2  = 10 + 12 - 5 * 2. With order of operations, we do the multiplication first so the equation is now 10 + 12 - 10 = 22 - 10 = 12

b. speed + miles * 3  = 10 + 5 * 3 and again, order of operations gives us 10 + 15 = 25

c. (speed + miles) * 3  = (10 + 5) * 3 = 15 * 3 = 45

d. speed + speed * miles + miles  = 10 + 10 * 5 + 5 = 10 + 50 + 5 = 60 + 5 = 65

e. (10 – speed) + miles / miles = (10 - 10) + 5 / 5 = 0 + 5 / 5 = 5 / 5 = 1
