Tom put 18 gallons of mid grade gas in his truck and filled up his empty five gallon gas tank with regular gas for his lawn mowe
LuckyWell [14K]

Answer:

Mid grade gas per gallon = $2.67

Regular gas per gallon = $2.37

Step-by-step explanation:

Let, x= mid grade gas, y=regular gas.

So, for 18 gallons of mid grade gas and 5 gallon of regular gas at $59.91, it can be expressed as,

18x+5y=59.91  ------------------(equation 1)

for 14 gallon of mid grade gas and 1 gallon of regular gas at 39.75, it can be expressed as,

14x+y=39.75  -------------------(equation 2)

y=39.75-14x  -------------------(equation 3)

Now substituting the value of y from (equation 3) in (equation 1) we get,

18x+5y=59.91

18x+5(39.75-14x)=59.91

18x+198.75-70x=59.91

52x=198.75-59.91

52x=138.84

x=\frac{138.84}{52}

x=2.67  -------------------------(equation 4)

Now substituting value of x from (equation 4) in (equation 3) we get,

y=39.75-14x

y=39.75-(14\times2.67)

y=39.75-37.38

y=2.37

Therefore price per gallon of mid grade gas is x = $2.67, and price per gallon of regular gas y = $2.37.

A runner completed a 26.2-mile marathon in 210 minutes. a. Estimate the unit rate, in miles per minute. Round your answer to the
ivanzaharov [21]

Answer:

Unit rate by which the runner completed the marathon is 0.13 miles per minute.

Step-by-step explanation:

A runner competed a marathon of 26.2 miles in 210 minutes.

we can get unit rate by unitary method.

∵ In 210 minutes a runner completes the distance = 26.2 miles

∴ In 1 minute runner will complete the distance = \frac{26.2}{210}

                                                                              = 0.125 miles per minute

                                                                              ≈ 0.13 miles per minute

Therefore, unit rate by which the runner completed the marathon is 0.13 miles per minute.
