b. write an equation where a number is multiplied by a variable, and a solution is -4/5

The needed equation is :

Step-by-step explanation:

A variable is defined as the UNKNOWN quantity whose value is determined on the basis of equation in which it is used.

A number or CONSTANT is defined as the KNOWN quantity whose value is NOT BASED on the basis of equation in which it is used.

Foe example C = 3, 5 ,-9,0 ...

Here, let us assume here the variable = m

And let us assume a number to be a CONSTANT C.

So, here Constant number C  is multiplied with variable, we get :  C x m

Also, the resultant is (-4/5)

So, The statement : a number is multiplied by a variable, and a solution is -4/5 is written as:

Hence the needed equation is

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

17.29 divided by 3 = 5.77

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.
