Answer:
1 6/8
Step-by-step explanation:
eight goes into fourteen 1 time with a remainder of 6
7x-3y=15 is the equation in standard form.
Answer:
It would take him 8 hours
Since every 50 miles takes 1 hour
We want to use elimination to solve
y = 0 (1)
x + y = 40 (2)
Multiply (1) by -1 to eliminate y.
-y = 0 (3)
Add (2) and (3).
x + y + (-y) = 40 + 0
x = 40
Answer: Multiply by -1.
