37.5 + 37.5 = 75 ; also, 37.5 x 2 = 75
Solve for a.
y=2x/a+2b
Multiply both sides by a.
ay=2ab+2x
Add -2ab to both sides.
ay+−2ab=2ab+2x+−2ab
−2ab+ay=2x
Factor out variable a.
a(−2b+y)=2x
Divide both sides by -2b+y.
a(−2b+y) / −2b+y = 2x / −2b+y
a = 2x / −2b+y
1325 250
------- = -------
x 10
1325(10) = 250x
13250/250 = 250x/250
x = 53
53 gallons are required to travel 1325 miles

Answer:
Angle E = 73 degrees
Step-by-step explanation:
Supplementary means it equals 180 degrees.
So to find x, you add the 2 equations.
2x + 15 + 5x - 38 = 180
which equals 7x + (-23) = 180 = 7x - 23 = 180
7x = 203 You move the -23 to the other side
203/7 = 29 So x = 29 degrees
So to find angle E, you put in 29 degrees for x.
2 x 29 + 15 = 73 degrees
angle EPF = angle DPG
=> 4x + 48deg = 7x
=> 3x = 48 deg
=> x = 16
=> angle EPF = 4(16) +48 = 112deg
