The answer is 88.8% how i got it is by:
30-18= 12 which is the number of member that had an average of 84
then multiply 12 times 84 = 1008 (keep this number)
last you multiply 18 by 92 which equals 1656
add 1008 and 1656 together and get 2664.
divide 2664 / 30 and you get the average of 88.8
Answer:
15
Step-by-step explanation:
The parallel lines divide the transversals proportionally.
The green length = 24 - c , then
= ( cross- multiply )
12(24 - c) = 20c ← distribute left side
288 - 12c = 20c ( add 12c to both sides )
288 = 32c ( divide both sides by 32 )
9 = c
Then
green length = 24 - 9 = 15
