Question

3f+2.9=4.4
Please help.

Answer 1

`\boxed{f=0.5,~(1)/(2)}`

Solution Steps:

______________________________

1.) Subtract 2.9 from both sides:

• 
  `2.9-2.9=` Cancels Out.

• 
  `4.4-2.9=1.5`.

- We subtract 2.9 from both sides because we need to get rid of any extra numbers on the opposite side of the equal sign. To do so, you do the opposite of what you see: We have a positive 2.9, so we subtract.

Equation at the end of Step 1:

• 
  `3f=1.5`.

2.) Divide both sides by 3.

• 
  `3f` ÷
  `3=f`.

• 
  `1.5` ÷
  `3=0.5`.

- We divide 3 from both sides because the 3 is attached to the variable and we need to get the variable alone. So to do so we have to divide by 3 on each side.

3.) Turn the decimal into a fraction:

• 
  `0.5=(1)/(2)`.

- 0.5 is equal to
`(1)/(2)` as a fraction.

Answer 2

f =0.5

Isolate the variable by dividing each side by factors that don't contain the variable.
