How many males and how many females would there be if the total enrollment is 15000?
Ratio is
90 males 15000 - x
------------- = ---------------
125 fem x
Then 90x = 1875000 - 125x, or 215x = 1875000
x = approx 8720 females
and 15000-8720, or 6279 males
If every male finds a dance partner, that would leave (8720-6279) females, or 2440, without dance partners. ;(
Check: is the male:female ratio near 90:125?
Is 6279:8720 approx equal to 90:125?
Yes. 0.72 (approx) = 0.72 (approx).
Answer:
Grace is right
Step-by-step explanation:
3(2-x)-2(6x-8)=
so:
3×2 is 6
3×(-x) is -3x
-2×6x is -12x
-2×(-8) is 16 because -×- equals +
3(2-x)-2(6x-8)
=6-3x-12x+16
= -15x+22
