Answer:

x=13,\:y=0

Step-by-step explanation:

Isolate x for 2x-3y=26: x=\frac{26+3y}{2}

\mathrm{Substitute\:}x=\frac{26+3y}{2}

\begin{bmatrix}3\cdot \frac{26+3y}{2}-4.6y=39\end{bmatrix}

Simplify

\begin{bmatrix}39-0.1y=39\end{bmatrix}

Isolate y for 39-0.1y=39: y=0

\mathrm{For\:}x=\frac{26+3y}{2}

\mathrm{Substitute\:}y=0

x=\frac{26+3\cdot \:0}{2}

\frac{26+3*0}{2}=13

x=13

\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}

x=13,\:y=0

IgorLugansk [536]

Answer:

1) 28.4 miles per gallon

2) 34 miles per gallon

3) the red car

Step-by-step explanation:

We have the following information:

  • <em>Blue car:</em>

<em>Travels 35 1/2 miles on 1 1/4 gallons of gasoline</em>

  • <em>Red car:</em>

<em>Travels 27 1/5 miles on 4/5 gallons of gasoline</em>

<em />

We want to know the unit rate for miles per hour, and to do it we have to divide the miles they travel by the gallons each car uses:

  • Blue car:

(35 1/2) / (1 1/4) = 28.4 miles per gallon

  • Red car:

(27 1/5) / (4/5) = 34 miles per gallon

The red car travels greater distance with 1 gallon of gasoline
