shutvik [7]

Answer:

Step-by-step explanation:

The appropriate relation is ...

  miles = (miles/gallon) × gallons

  distance = (31 mi/gal)×(24 gal) = 744 mi

Find the value of x. Then find the measure of each labeled angle
Artyom0805 [142]

Step-by-step explanation:

Question 10 :

3x + 6 = 4x – 12 ( reason: corresponding angles due to parallel lines)

simplify and get x, thus x = 18

to find 3x + 6 or 4x - 12(which is both the same),

3(18) + 6 = 60° , 4(18) - 12 = 60°

Question 11:

2x + 24 + x = 180 ( reason: interior angles due to parallel lines)

simplify again to get x, you will get x = 52

then find the individual by subbing in the value of x into the equation.

so 2x + 24 = 2(52)+24 = 128° and x = 52°
