Answer:
19
Step-by-step explanation:
To get the total miles you drove first, you need to do 84947 (number after the trip) - 84679 (the number before it. You get 268.
Next you need to find out how many miles per gallon. 268/14 which will equal to 19.142, which you can round to 19.
Answer:
1. Substitute y = -3x +4 for y in the first equation
2. Combine like terms and isolate x
3. Substitute in x into the 2nd equation to get y
Step-by-step explanation:
1. Substitute y = -3x +4 for y in the first equation
2x- (-3x+4) = 6
2. Combine like terms
5x -4 = 6
5x -4 +4 = 6+4
5x=10 Divide by 5 to isolate x
5x/5 =10/5
x=2
3. Substitute in x into the 2nd equation to get y
y = -3x +4
y = -3(2) +4
y = -6+4
y=-2
(2,-2)
