Agenerator runs for 2 1/2 h and uses 4 3/8 gal of fuel. how many gallons of fuel did the generator use each hour?

The generator uses 1.75 gallons per hour or 1 3/4.

In order to find this, we need to divide the number of gallons by the number of hours. It's easier if we first turn them into decimals.

2 1/2 hours = 2.5 hours

4 3/8 gal = 4.375 gallons.

Then we divide.

4.375 gallons/ 2.5 hours = 1.75 gallons per hour.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
