There is around 6,500 languages around the world
Trapezoid Area = (Base1 + Base2) (h/2)
so A = (3x + 5x )(6x/2)= 24x^2
It says the elevator's can hold minimum 3000 pounds and how many of a 150 pound box can fit without going over the 3000 pound.
So,
Ralph (r): a + 5
Alphonse (a): a
Ralph + Alphonse = Total
(a + 5) + (a) = 73
2a + 5 = 73
2a = 68
a = 34
Ralph: a + 5 = 34 + 5 = 39
Answer: Ralph has 39 marbles, Alphonse has 34 marbles
This is the Communative property of multiplication
