Question

18.6/?=0.02
2.2/?=0.16

Answer 1

18.6/x=0.02

We move all terms to the left:

18.6/x-(0.02)=0

Domain of the equation: x!=0

x∈R

We add all the numbers together, and all the variables

18.6/x-0.02=0

We multiply all the terms by the denominator

-(0.02)*x+18.6=0

We multiply parentheses

-0.02x+18.6=0

We move all terms containing x to the left, all other terms to the right

-0.02x=-18.6

x=-18.6/-0.02

x=+930

2.2/x=0.16

We move all terms to the left:

2.2/x-(0.16)=0

Domain of the equation: x!=0

x∈R

We add all the numbers together, and all the variables

2.2/x-0.16=0

We multiply all the terms by the denominator

-(0.16)*x+2.2=0

We multiply parentheses

-0.16x+2.2=0

We move all terms containing x to the left, all other terms to the right

-0.16x=-2.2

x=-2.2/-0.16

x=13+0.12/0.16

Answer 2

Step-by-step explanation:

$1) \\ \frac{18.6}{?} = 0.02 \\ ? = \frac{18.6}{0.02} = 9.3 \\ 2) \frac{2.2}{?} = 0.16 \\ ? = \frac{2.2}{0.16} = 1.37$
