Answer:
<u>The answer is m = 5</u>
Step-by-step explanation:
Let's solve the proportional equation, this way:
3/m-2 = 7/m+2
3 * (m + 2) = 7 * (m - 2) [Lowest common denominator (m + 2) * (m - 2)]
3m + 6 = 7m - 14
-4m = -14 - 6 (Like terms)
-4m = -20
m = -20/-4
m = 5
B
as [tex]\cos(\theta)=\srqt{1-\sin^2(\theta)}\[tex]
and since theta is in second quadrant, where cosine is negative,
so -√(1-z²)
hope this helps you
have a great day
8 male, 12 female
male = x
female = 2x - 4
2x - 4 + x = 20
3x - 4 = 20
3x = 24
x = 8
2(8) - 4 = 12
there are 8 male, 12 female
