Answer:
15.4 gallons .
Step-by-step explanation:
The rate of gas used = 380/14 = 27.14 gallons per gallon.
So for each gallon used you drive 27.14 miles.
So number of gallons used when travelling 418 miles = 418/27.14
= 15.4 gallons .
The slope intercept form is y=2x-2 and the y intercept is -2 and the x intercept is 1
Answer:
1.95 or 1 19/20 Hope this helps!
Step-by-step explanation:

So do the parenthesis first. (3 1/3 * 1) is 3 1/3
Next, Division. 6 1/2 divided by 3 1/3 is 1.95 or 1 19/20
The sum of all angles in a triangle is equal to 180°, so....
Equation 1:
(3y-20)+2y+(x+13)=180
5y+x-7=180
x=187-5y
A straight line angle is 180°, so....
Equation 2:
2y+3x+9=180
Substitute x=187-5y into Equation 2:
2y+3(187-5y)+9=180
2y+561-15y+9=180
-13y=-390
y=30
Substitute y=30 into Equation 1:
x=187-5y
=187-5(30)
=37
Answer: x=37°
