consecutive integers have a difference of 1 between them
let the brothers have ages n , n + 1 and n + 2 thus
n + n + 1 + n + 2 = 96
3n + 3 = 96
subtract 3 from both sides of the equation
3n = 96 - 3 = 93
divide both sides by 3
n =
= 31
The ages are 31 , 32 and 33
25 days
First, start with an equation
100+8x= kittens weight
(X representing the days)
Since you’re trying to figure out the number of days it takes the kitten to triple it’s weigh you multiply it’s initial weight by 3 (100•3)
Then, you output 300 into the equation and solve
A cardinal number of a set is the number of elemenents it contains. Therefore the cardinal number of A is equal to 5.
