Hank's pickup can travel 80 miles on 5 gallons of gas. how many gallons will hank's pickup need to travel 64 miles?

4 gallons of gas

Step-by-step explanation:

80/5 = 64/x

Simplofy 80/5 to 16/1.

Divide 16 by 16 and 64 by 16 to get 4.

Your proportion will now look like this.

1/1=4/x

x=4

Hank needs 4 gallons of gas.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
