Answer:715 ways
Step-by-step explanation:
Given
There are 12 sophomores
8 Juniors
and 13 seniors
Ms. bell create a 4- member committee of seniors
No of ways of selecting 4 seniors out of 13
So, there are 715 ways of forming a 4 member senior committee.
Y= 3 -x (1)
3x + 4y = 1 (2)
Substitute (1) for y in (2)
3x + 4(3 - x) = 1
Expand, simplify and then solve for x
3x + 12 - 4x = 1
3x - 4x = 1 -12
-x = -11
x = 11
The unit rate would be how many miles they drove in 1 hour.
To find that, divide total miles driven by total hours driven.
392 miles / 7 hours = 56 miles per hour.
The unit rate is 56 miles per hour.
