Step-by-step explanation:

Set up and solve an equation of ratios.  One such equation would be:

5         40

--- = ------------

3      2x + 10

Cross multiplying, we get:

10x + 50 = 120, or 10x = 70.  thus, x = 70/10, or x = 7.

What is the degree measure of FEG?<br> A 20°<br> B 31°<br> C 56°<br> D<br> 124°
Blizzard [7]

Answer:

C) 56

Step-by-step explanation:

DEG and FEG are on a straight line forming 180 degree.

Set your formula up as

180 = (3x+31)+(2x-6)

180 = 3x +2x +31 - 6

180 - 31 + 6 = 5x

155 = 5x

155/5 = x

31 = x

Now substitute 31 in place of x

FEG = (2*31-6)

FEG = 56

6) Parking lot A charges $19.00 to enter the parking lot plus $1.50 per hour
Olegator [25]

Answer:

4 Hours.

Step-by-step explanation:

You would set this up as an equality where x represent hours

19.00 + 1.50x = 14+2.75x

You then get the x on one side by subtracting 14 from both sides and 1.50x from both sides.

5 = 1.25x

Divide both sides by 1.25 to x by itself.

4 = x
