Answer:

9 square units

Step-by-step explanation:

Draw a rectangle around the triangle. The rectangle is 4 units tall by 6 units wide. The area of the triangle equals the area of the rectangle minus the triangles in the corners.

A = (4)(6) − ½(2)(4) − ½(1)(4) − ½(3)(6)

A = 24 − 4 − 2 − 9

A = 9

If a car can travel 220 miles on 12 gallons of gas, how many gallons

vampirchik [111]

Set up a ratio of known to unknown:

Let X = the amount of gas needed for 500 miles:

220/12 = 500/x

Cross multiply:

220x = 6000

Divide both sides by 220:

X = 6000 / 220

x = 27.27 gallons (round answer as needed).
