Answer:
235
Step-by-step explanation:
The population equation is given as P= 2.726x + 126.189
-To find the number of years since 1980, we subtract the start year from the current year(2020):
X=2020-1980=40
We substitute the x value in the population equation to find the current population:
P=2.76x+126.189 but x=40
P=2.76(40)+126.189=235.229
Rounding off then the population in the current year is 235
Answer:
yes

Answer:
y < 5/3
Step-by-step explanation:
3y + 5 < 10
Let's subtract 5.
3y < 5
Okay. We have something manageable. Let's divide by 3.
y < 5/3
That's our answer.
Answer:
63
Step-by-step explanation:
Just input 3 instead of x, you would get 14(3) + 21 = 63
Let's see.
4x/5 + 4/3 = 2x
First we have to make each denominator the same, so I'll multiply 4x/5 by 3/3, 4/3 by 5/5, and 2x by 15/15
Now we have 12x/15 + 20/15 = 30x/15
With everything in the same denominator we can solve the new equation of
12x + 20 = 30x
20 = 18x
10 = 9x
X= 10/9
