A car has 15 gallons of gas in its tank. The car travels 35 miles per gallon of gas. It uses 135 of a gallon of gas to go 1 mile

STALIN [3.7K]

Answer:

525 miles

Step-by-step explanation:

Two unit rates are given in this problem:

miles per gallon
gallons per mile

Since we want to find miles, the appropriate rate to use is miles per gallon:

distance = mile/gallon x gallons

distance =35 miles/gallon x 15 gallons = 525 milles

The car can travel 525 miles on 15 gallons of gas.

What is the positive solution to this equation? 4x^2+ 12x = 135 Record your answer and fill in the bubbles on your answer docume

Ira Lisetskai [31]

Answer:

$\frac{9}{2} or 4.5$

Step-by-step explanation:

4x^2+ 12x = 135

D=b²−4ac=122−4(4)(−135)=144+2160=2304=48²

$x_{p}= \frac{-12+48}{8} =\frac{36}{8}=\frac{9}{2}=4.5$
