Contributed by: Sonnier

Coefficients is the

 numerical factor of a term that contains a variable.

True or False

If the coefficient

is a decimal, divide each side by the coefficient.

 

True or False

1.3n = 3.9

 

1.3n ÷ 1.3= 3.9 ÷ 1.3

 

              n=

2.5x = 30

 

2.5x ÷ 2.5 = 30 ÷ 2.5

 

               x =

.3c= 12

 

.3c ÷ .3 = 12 ÷ .3

 

           c =

6.4 = 0.8k

 

6.4 ÷ 0.8 = 0.8k ÷ 0.8

 

             k =

7.5 = 25s

 

7.5 ÷ 25 = 25s ÷ 25

 

            s =

100 = .25x

 

100 ÷

= .25x ÷
400 =

.9k = 81

 

.9k ÷

k =

= 81 ÷

13.6 = .2s

 

13.6 ÷

 = .2s ÷
= s
