The following do not have a solution:
• 6x+1=3(2x-4)
• -4(x+3)=4(-x-1)
Right change flip it's simple
Answer:
42 mph
Step-by-step explanation:
From 2 p.m. to 6 p.m. 4 hours passed, so the truck and the motorcycle were on the road for 4 hours until they met.
Motorcycle in 4 hours at a constant speed of 45 mph travelled

The distance between the motorcycle and the truck is 348 miles, so the truck travelled

If x mph is truck's speed, then

1) Find the mean of the following numbers: 5, 11, 8, 8, 7, 4, 10, 9, 7, 7, 6
SashulF [63]
Mean = 5+11+8+8+7+4+10+9+7+7+6 divided by the number of observations which is 10
Therefore, mean = 73/10
Mean = 7.3
