Answer:
The answer is D. 15 gallons of gas were used.
Each side of the triangle has a little line through them. This means all 3 sides are equal, so all three inside angles would also be equal.
The three inside angles of a triangle need to equal 180 degrees.
Divide 180 by 3 to find the inside angle for each angle:
180 / 3 =60.
Each inside angle needs to be 60 degrees.
Set the equation with x in it to 60 and solve for x:
2x-4 = 60
Add 4 to each side:
2x = 64
Divide both sides by 2:
x = 64/2
x = 32
The way I'm reading this, your equation would be 5+0.75x=y.
If 2, 5, 8, and 10 are units, then you would plug those in individually and solve, like this:
5+0.75(2)= 6.5
5+0.75(5)=8.75
5+0.75(8)=11
5+0.75(10)=12.5
Hope this helps!
