Answer: angle abc
Step-by-step explanation:
<span>From 2000 to 2005,the population decrease d by 4%. What was the town's population in 2005?
The first thing we want to look at is that from 1995 to 2000, the population increased by 15% (from 4,500.) So that means we multiply 4,500 times 15% to get 15% of 4,500.
.15*4,500=675 (.15 is the same thing as 15%)
So we see it increased by 675.
4,500+675=5175
So in 2000, there were 5,175 people
So now we do the same thing for 2000 to 2005.
The population has decreased by 4% (or .04)
Now to see what 4% of 5,175 is we multiply is by 4%
.04*5175=207
So now if it has decreased by 207 (4% of the population in 2000)
Now we subtract that number from the population in 2000
5175-207=4968
In 2005 there are 4968 people.

Answer:
39
Step-by-step explanation:
His number is x.
"If you subtract 19 from my number"
x - 19
"and multiply the difference by - 7"
-7(x - 19)
"the result is -140."
-7(x - 19) = -140
Divide both sides by -7.
x - 19 = 20
Add 19 to both sides.
x = 39
Answer: The number is 39.
