Marco paid $36.89 for 8.6 gallons of gas. what is the price of 1 gallon of gas?

When you divide 36.89/8.6, you get should $4.29 for 1 gallon of gas.

$4.29

Step-by-step explanation:

It is $4.29 because you need to find the price of one gallon, so you just divide the numbers $36.89 by 8.6 gallons which is 4.289 and if you round it it is $4.29 per gallon / 1 gallon.

(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
