For each of the equations below, choose the best answer from the four choices given.
If there are 2.2 pounds in 1 kilogram, how many pounds are there in x kilograms? [Basic]
a. x/2.2
b. 2.2x
c. 2.2 + x
d. 2.2/x - ANS-B. 2.2x
2.2 lbs/1 kg = a lbs/x kg
a=2.2x
Formula: The volume of the right circular Cylinder is V=(3.14)^2h
if r= 2b and h= 5b + 3, what is the volume of the cylinder in terms of b? [Basic]
a. 10mb^2 + 6(pi)b
b. 20(pi)b^3 + 12(pi)b^2 - ANS-b. 20(pi)b^3 + 12(pi)b^2
v=(pi)(2b)^2(5b+3)
=(pi)(4b^2)(5b+3)
=4(pi)b^2(5b+3)
=20(pi)b^2+12(pi)b^2
If 7p - 4 = 8, what is the value of p? [basic]
a. 4/7
b. 7/12
c. 12/7
d. 7/4 - ANS-c. 12/7
7p - 4 = 8
+4 +4
7p = 12
p=12/7
Last year, a bakery sold w loaves of bread. This year, the bakery sold three more than twice the
number of loaves of bread sold last year. If next year the bakery plans on selling twice the
