Find the speed of the truck:
140 miles / 3.5 hours = 40 miles per hour
The car was 20 miles an hour faster: 40 + 20 = 60 miles per hour.
Divide distance by speed: 140 miles / 60 miles per hour = 2 1/3 hours
Answer: 2 1/3 hours
Answer:
y=-5/2x-3
Step-by-step explanation:
put the 2 points in slope to get -5/2. then use point slope form(y-y1)=m(x-x1) and put -8 in y1, 2 in x1, and -5/2 in m
49^(3/2)
This is the same as (sqrt49)^3
7^3 = 343
Answer:
An x-coordinate is the x value in an ordered pair, which is just two mathematical objects, such as numbers, paired together. Usually, the x-coordinate is the first number in that pair. For instance, in the ordered pair (2,5), the x-coordinate would be '2.
