Answer:
9) -25/21
11) 14
Step-by-step explanation:
In each case, subtract the y-coordinates. Subtract the x-coordinates in the same order. Divide the difference in y by the difference in x.
9)
y-coordinates: -10 - 15 = -25
x-coordinates = 6 - (-15) = 21
slope = (difference in y)/(difference in x) = -25/21
11)
y-coordinates: -20 - 8 = -28
x-coordinates = 3 - 5 = -2
slope = (difference in y)/(difference in x) = -28/(-2) = 14
Answer:
315 inches long
Step-by-step explanation:
180 x .75= 135 <--- that is 75% of 180
then add the two numbers
180 + 135
you add them because the original length of the car is 180 inches and the truck is 75% longer.
180 + 135= 315
It's C. 12,400. This is because 800 + 0.09x= 1916 0.09x= 1,116 x= 12,400.
Hope this helped!
Answer:
Step-by-step explanation:
Remember that
we have
In this problem
b represent the 100%
so
using proportion
Find out what percent of b represent a
Let
x -----> the percentage of b
Convert to mixed number
2 laps
1 lap would be 1/3 a mile therefore 2 laps would be 2/3 a mile
