A car gets 25 miles per gallon. How many gallons of gas are needed for the car to
go 180 miles?

7.2

Step-by-step explanation:

182÷25=7.2

so say about 7

X=7.2

Step-by-step explanation:

25/1=180x

x = 7.2

Solution by Cross Multiplication

For the equation

251=180x

The cross product is

25×x=1×180

Solving for x

x=1×18025

and reducing

x=7.2

Solution by Proportion

Since the equation is an equality

If

180 ÷ 25 = 7.2

Then it is true that

x ÷ 1 = 7.2

Solving for x

x = 1 × 7.2

x = 7.2

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
