Answer:
The cost of 5 gallons of fuel would be 5x assuming the cost of 1 gallon to be x.
Step-by-step explanation:
An old truck has a fuel efficiency rating of 12 mpg.
We have to find the cost of gasoline that will be used up after we drive 60 miles.
To drive 60 miles , it uses 5 gallons.
let the cost of 1 gallon of fuel be x.
We have to find the cost of 5 gallons of fuel.
So the cost of 5 gallons of fuel = 5
= 5x
The formula for circumference is 2×pi × r
We are given the diameter of 2 meters which means the radius is 1 meter. We will use 3.14 for pi.
2 × pi × r =
2 (3.14)(1) =
6.28
The distance around the barbecue pit is
C. 6.28 meters
Answer:
(x + 7) 5 = 8
Step-by-step explanation:
A number = x
Sum = addition
(x + 7)
Five times would be
(x + 7) 5
And if equivalent to 8 then…
(x + 7) 5 = 8
I'm guessing you are asking what a number raised to the third power would be called, in that case it'd be called cubed :)
