Question

Solve for r.0.5(r +2.75) = 3

Answer 1

The given equation is,

`0.5\mleft(r+2.75\mright)=3`

To solve the above equation for r, first divide both sides of the equation by 0.5.

`\begin{gathered} (0.5\mleft(r+2.75\mright))/(0.5)=(3)/(0.5) \\ r+2.75=6 \end{gathered}`

Subtract 2.75 from both sides of the above equation.

`\begin{gathered} r+2.75-2.75=6-2.75 \\ r=3.25 \end{gathered}`

Therefore, the value of r is 3.25.
