A gas station has a car wash the gas coast X dollars per gallon then you are charged a flat fee of y dollars for a car wash two cars fill up their tank with and get a car wash one car uses 8 gallons of gas and pays 22.80 the other car use 6 gallons of gas and pays 18.60 find the cost per gallon of gas and the flat fee for the car wash

The cost of the gas per gallon is $2.1 and the cost of the car wash is $6.

Step-by-step explanation:

Given the cost of the gas per gallon is dollars. And the charge of car wash is dollars.

Also, it was given that two cars fill up their tank and go for a car wash. We can write linear equation for each case.

One car pays $22.80. It uses 8 gallons gas and go for car wash.

Equation (1)

The other car pays $18.60. It uses 6 gallons gas and go for a car wash.

Equation (2)

substitute this value of in equation (1) we get,

Now, to find the value of we will plug value of in

So, the cost of the gas per gallon is $2.1 and the cost of the car wash is $6.

answer: 2/4

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
