We are given: Initial amount of the gas = 30 gallons.
Milage of the Troy’s truck = 21 miles per gallon.
Number of gallons of gas used in 1 miles = 1/21 gallons.
Let us assume, number of miles Troy truck travel = m miles.
Number of gallons of gas used in travelling m miles = m * 1/21 = 1/21 m.
And number of gallons of gas left after travelling m miles = g gallons of gas.
Number of gallons of gas = Total gas present initially - Number of gallons gas used to travel m miles.
Therefore, we can setup an equation.
g = 30 - 1/21 m.
What Are you talkin bout?
R + b = 49
b = 6r
r + 6r = 49
7r = 49
r = 49/7
r = 7 <== he has 7 red beads
b = 6(7)
b = 42 <== he has 42 blue beads
