If: b/5+b/3 = 10 then b works out as 18.75
commutative property
Should the question read: "In math, a over 5 equals b over 7 equals 8 over 3. Does a plus b equal 31.99?"Do you mean a/5 = b/7 = 8/3?If so, we can look at a and b separately.a/5 = 8/3a = 5*(8/3)a = 40/3a = 13.33b/5 = 8/3b = 7*(8/3)b = 56/3b = 18.67It looks as though you have added a and b together to get 13.33 + 18.67 = 32 (if you did b=18.66 then you would get 31.99 but it should be 32).
b= 4
( A2 / B1/3 ) x (B / A1/2 ) = ( A2 / A1/2 ) x ( B / B1/3 ) = A3/2 x B2/3
If: b/5+b/3 = 10 then b works out as 18.75

Well, honey, when b equals 9, 24 over b plus 8 is just 24 over 9 plus 8. And if you do the math, that's 24/9 + 8, which simplifies to 8/3 + 8. So, the answer is 32/3. Hope that clears things up for ya, sugar!
b= 4
A + B + C
a+b+2+3=5+a+b
a(b+3)+b(b+3)
This expression can be factored. ab + 3a + b2 + 3b = a(b + 3) + b(b + 3) = (a + b)(b + 3)
Six take away B times five B plus 30 equals 1. This is a math problem.
( A2 / B1/3 ) x (B / A1/2 ) = ( A2 / A1/2 ) x ( B / B1/3 ) = A3/2 x B2/3
The cube of A plus B is either A**3 + B or (A + B)**3 depending on what you intended to be cubed.
