BD=10 because it is symmetrical to AD.
Answer:
commutative property:
A + B = B + A
So we have
3 + (5 + 7) = (5 + 7) + 3
Now distributive means that:
A + (B + C) = (A + B) + C
So (5 + 7) + 3 = 5 + (7 + 3)
now the equation is easier to solve, because 7 + 3 = 10
5 + (7 + 3) = 5 + 10 = 15
That would make it a square root, so I'd say 2
Answer:
from the given info
you can know that there were 16 red ones. (2/3)*24
and 8 green apples
and her classmates ate 3/4 of red ones i.e.
(3/4)*16
=12
and 1/2od green
i.e.
(1/2)*8
=4
and now the total eaten apples
= 12+4
=16
and the remaining number are
24-16
=8
