Answer:
a) 98
b) directly
c) k = 14 pages per hour
Step-by-step explanation:
a) In order to answer the first question, we must assume that the number of pages varies directly with the amount of time. Further, we must find the constant of variation:
p = kt
56 = k(4)
k = 56/4 = 14 . . . . pages per hour
Then in 7 hours, the student will read ...
p = 14(7) = 98 . . . pages
__
b) As we said in part (a), the variation is direct.
__
c) As we found in part (a), the constant of variation is 14 pages per hour.

Answer:
4x−5y=−10 hopefully this helps
84 + 99w = 1150
99w = 1150 - 84
99w = 1066
w = 1066/99
w = 10.76......so she can buy 10 watches maximum
There are no choices, but anything that has those option are right.
