The machine was operated for 4.5 hours
A machine uses gasoline at a rate of 1/5 gallon per hour
The number of hours it will take the machine to use 9/10 gallon can be calculated as follows
1/5 = 1
9/10= x
cross multiply
1/5x= 9/10
0.2x= 0.9
x= 0.9/0.2
x= 4.5
Hence the machine was operated for 4.5 hours

-3 degrees celsius because -7 + 2 = -5, -5 + (-4) = -9, and -9 divided by 3 = -3.
Function of equation is x * 6 = y
Using this, 7 x 6 = 42.
Your answer is c, or 42.
Step-by-step explanation:
2/3 is not greater than 5/7 and the answer to the question "Is 2/3 greater than 5/7?" is no. When comparing fractions such as 2/3 and 5/7, you could also convert the fractions (if necessary) so they have the same denominator and then compare which numerator is larger.
