Answer:
1. County B
2. (I'm going to keep working on an answer for this one).
Step-by-step explanation:
A. 25 ppl × 100 sq miles = 2500
100 ppl × 40 sq miles (25 kilometers square) = 4000
County B
N+n<8
is that what you are looking for?
Step-by-step explanation:
We have to get one positive 7y so,
4x-7y=5
9x-7y=-15
multiply anyone of the equation by -1. I choose the first one so,
4x+7y=-5
9x-7y=-15
we can now cancel the y's so the equation will be left with
-4x=-5
9x=-15
add the equations
5x=-20
divide by 5 n u get
x=-4
now plug in the x value in any one of the
equations
I choose the first one so,
4(-4)-7y=5
-16-7y=5
add 16 to both sides
-7y=21
divide by -7
y=-3.
finally check.
Answer:
30x25/100
25%=7,5$
30+7,5$=37,5$
The original price was 37,5 because you had to first find out what was 25% in $ to then do the opposite of a sale since we are finding the original price so we have to add it to 30$ since 30$ was the price after the sale.
Hope this helps, have a good day!
