Question

a car travels 720 miles on 12 gallons of gas what is the constant of proportionality how many gallons would be used on a 1000 mile trip

Answer 1

=50/3:720÷12=1000÷, 0 x=0 not equal reduce the fraction 60=1000/xmultiply both sides of the equation by the common denominator :60x=1000x/xreduce the fractions:60x=1000divide both sides of the equation by coifficient of variable:x=1000/60cross out the common factor:x=50/3find the intersection:x=50/3get the result:x=50/3ANSWER:X=50/3
