If we multiply the first equation by 2 we get
2x - 4y = 12
but the second equation is
2x - 4y = 10
2x - 4y can't have 2 different values so the are no solutions
Answer:
7 cm
Step-by-step explanation:
it is a square so sqrt(49)=7, and the side lengths are 7
Answer:
12 miles in 4 hours is 3 mph
52-12=40 miles left
40 miles at 5 mph would take 8 hours
8+4=10
it took 10 hours to finish the trip.
360 degrees / 24 hours = 15 degrees per hour
150 degrees / 15 degrees per hour = 10 hours
Answer: 10 hours
