Answer:
The possible number of trees in each of the rows could be any amongst the following numbers;
1,2, 5 and 10
Step-by-step explanation:
Here, we want to know the possible common number of trees in each rows
For the girls, we have 30 trees
For the boys we have 50 trees
What we simply do here is to get the factors of both;
That will be listed as follows;
for 30;
1,2,3,5,6,10,15 and 30
for 50,
1, 2 , 5,10, 25 and 50
So the possible number of trees in each of the rows are;
1, 2 , 5 and 10
So.. first off.. let's keep in mind that if 30% of acid is there in a solution, say the solution is some amount of liquid and 30% of that total liquid only is the acid, so if the amount of the liquid is say "x", then 30% of that is just (30/100) * x, or 0.3x.
now, we'll do the same for the 55% and the 45%, use the decimal format to get how much quantity in the substance is of acid.
now, whatever "x" and "y" are, we know that
x + 60 = y, and we also know that
0.3x + 33 = 0.45y.
This question is so ez. It 22
