Answer:
A) 30x+32=560
Step-by-step explanation:
Since mikey has already read 32 pages last week and would read 30pages per hour, then in order to get 560
You do:
32(pages)+30(pages*hour)*x(hours) =560 pages.
Answer:
0.857 miles in 1 hour
Step-by-step explanation:
It is given that,
A crew of highway workers paved 12 mile in 14 hour.
We need to find how much will they pave in 1 hour if they work at the same rate.
14 hours = 12 miles
To find how much they pave in 1 hour, we must divide 12 by 14 as follows :
Hence, they pave 0.857 miles in 1 hour.0.857 miles in 1 hour.
Company A charges $75.50 and 14¢ per mile, then for x miles, Company A charges 75.5 + 0.14x dollars
Company B charges $30.50 and 9¢ per mile, then for x miles, Company B charges 30.5 + 0.09x dollars
Subtracting the second equation to the first one,
75.5 + 0.14x
-
30.5 + 0.09x
----------------------
45 + 0.05x
For x miles, Company A charges 45 + 0.05x dollars more than Company B.
For #1 the answer would be ; " y = - x - 4 "
( you just have to plug in the given numbers to the slope intercept form )
