; Simplified =
Let "Zoe" = z
Let "Luke" = x
x = 16/2 + 3 is your equation
You're expression is
~
3x(4x4 – 5x)
= 12x^5-15x^2
12.42
12°+.42(60)
12°25.2'
12°25'+.2(60)
12°25'12"
First you multiply 4*n and n=3 so 4*3 = 12
then you have 9+12-1
9+12= 21
21-1=20
so your answer would be 20
The original ratio is 5:7 then 2 boys join and 1 girl as well making the new ratio 4:5
