Answer:
B. F:S = 17 to 19; S:F = 19 to 17
Step-by-step explanation:
Put the corresponding numbers in the corresponding parts of the ratio you want to write:
freshmen to sophomores (F:S)
17 to 19
___
sophomores to freshmen (S:F)
19 to 17
These pairs of numbers match choice B.
Multiply by 4
that way you can figure out how many pages per hour were read. so 98 times 4 is 392. so it is 392 pages per hour
48.. i don’t have the work but hopefully someone else does
The factors of 4 are 1, 2, and 4 .
The factors of 9 are 1, 3, and 9 .
Mult. the 2nd eqn by 6 and then add this "new" equation to the 1st given eqn:
-6x + y = -2
6x -18y = 54
--------------------
-17y = 52, or y = -52/17. Subst. this value of y into either equation to find the value of x.
