Gas mileage is the number of miles you can drive on a gallon of gasoline. a test of a new car results in 440 miles on 20 gallons of gas. how far could you drive on 60 gallons o gas? what is the car’s gas mileage?

Step-by-step explanation:

20 : 440 = 60:x

Product of means = 440*60

Product of extremes = 20*x

20*x = 440*60

x = 440*60/20 = 440*3

x = 1320 miles

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
