Answer:
6/25
Step-by-step explanation:
6 numbers (from 1 - 25) are less than 7. There are 25 numbers in total. This makes the probability 6/25.
Answer:
-5 is the coefficient of b
Step one: Add 8m + 13m
21m.
21m = 42.
Step two: Divide 42 by 21.
m = 2.
Answer:
a^3 - b^3.
Step-by-step explanation:
Area = length * breadth
= (a - b)(a^2 + ab + b^2)
= a(a^2 + ab + b^2) - b(a^2 + ab + b^2)
= a^3 + a^2b + ab^2 - a^2b - ab^2 - b^3
Note: the 4 middle terms cancel out. So the answer is
a^3 - b^3.
m = 4b+3 mikes age
m +b <138 mike +brother less than 138
4b+3+b<138
5b +3< 138
b< 135
b <27
The oldest the brother can be is 26
