On a number line, a number, b. is located the same distance from 0 as another number, a, but in the opposite direction. The number b varies directly with the number a. For example b= 2 when a=-2 Which equation
represents this direct variation between a and b?
b=-a
-b=-a
b-a=0
b(-a) = 0

easy math just plug in a and b

step-by-step explanation:

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
