Answer:
in 36 years
Step-by-step explanation:
in 36 years, Max will be 54 YEARS OLD and Leo will be 18 YEARS OLD.
54÷18= 3
this means that when max is 54, he will be 3 times older than leo
it can also be when Leo is 6 and Max is 18 because:
18÷6=3 means max is already 3 times older than leo
Answer:
Step-by-step explanation:
There is no answer that’s already in correct form
Since there are more parakeets than canaries, it is not possible to have only 1 of each bird in each cage <u>and</u> have the same number of birds in each cage.
He could use 42 cages, putting a canary in with the parakeet in 18 of them. Then he would have 18 cages with 2 birds each, and 24 cages with 1 bird each.
The only way to have the same number of birds (1) in all cages is to have 60 cages, 42 of which have 1 parakeet, and 18 of which have 1 canary.
_____
If more than 1 of each kind of bird can be put in the cage, the collection of birds could be put into 6 cages, each of which would be home to 7 parakeets and 3 canaries.
Step-by-step explanation:
The coefficients of the y terms are -3 and 2. The least common multiple of 3 and 2 is 6. So multiply the first equation by 2 and the second equation by 3, so that the y terms have a coefficient of 6.
4x − 6y = 42
-18x + 6y = 21
The signs are opposite, so add the equations together.
-14x = 63
x = -9/2
It would be between 11 and 12 because 11 times 11 = 121 and that is smaller than 123. Also 12 times 12 is 144 and 12 a whole number.
