Answer:
60 people left each year so -60
Step-by-step explanation:
-300 is the total population change over the past 5 years
The population decreased.
Divide 300/5 to find the amount of people who left each year
300/5= 60
60 people left each year.
The change in the towns population is (-60)
15 books in 6th grade
18 books in 7th grade.
% Change = (18 - 15) /15 * 100%
= 3/15 * 100%
= 1/5 * 100% = 20%
Percent change = 20%.
Answer:
-15
Step-by-step explanation:
We proceed as follows;
In this question, we want to fill in the blank so that we can have the resulting expression expressed as the product of two different linear expressions.
Now, what to do here is that, when we factor the first two expressions, we need the same kind of expression to be present in the second bracket.
Thus, we have;
2a(b-3) + 5b + _
Now, putting -15 will give us the same expression in the first bracket and this gives us the following;
2a(b-3) + 5b-15
2a(b-3) + 5(b-3)
So we can have ; (2a+5)(b-3)
Hence the constant used is -15
204/68=3, 207/69=3, 210/10=3, 213/71=3, 216/72=3, 219/73=3
