Answer:
x them by 60 because there are 60 minutes in an hour.
Step-by-step explanation:
Answer:
y=salary=32.000
x=years
salary after 15 years y+1800x
32000+1800(15)
32000+27000=59000
Step-by-step explanation:
An appropriate unit for Abedabun's purpose would have to include $ for the car's maintenance COST and a large distance measurement because we are talking about cars (and they can travel a long distance).
The best answer would be:
C) $/km
$ for the cost and km for the distance the car is driven.
7x-5y=21 when x=4 from the coordinate point of (4,y)
Next,
7x-5y=21
Substitute x with 4
7(4)-5y=21
28-5y=21
Add 5 to each side
28-5y+5y=21+5y
28=21+5y
Subtract 21 to each side
28-21=21+5y-21
7=5y
Divided 5 to each side
7/5=5y/5
y=7/5
Or
y=1 2/5
Check:
7x-5y=21
Substitute x with 4 and y with 7/5
7(4)-5(7/5)=21
28-7=21
21=21. As a result, (4,7/5) is your correct answer. Hope it help!
