How do i solve this rational expression r-4/5r=1/5r+1

NNADVOKAT [17]

r - 4/5r = 1/5r + 1

Subtract 1/5r from each side: r - 4/5r - 1/5r = 1

Combine all the 'r' terms on the left side:

 r - 5/5r = 1

 r - r = 1

 0 = 1

There is no value of 'r' that can make ' 0 = 1 ' a true statement.
So the equation has no solution.

Grant spent 2.50,$4.00,$4.25, and $3.25?On breakfast one week.The next week he spent $6 more in total for the 4 breakfasts than

masha68 [24]

We have been given that Grant spent $2.50, $4.00, $4.25, and $3.25 on breakfast in one week. The next week he spent $6 more in total for the 4 breakfasts than the week before. We are asked to find increase in the mean of second week.

Since Grant spent $6 more than last week, we will divide 6 by 4 to get how much mean of second week breakfast expenditures increased with respect to first week expenditures.

$\text{Mean increase in second week breakfast expenditure}=\frac{6}{4}$
