Answer:
Step-by-step explanation:
(-3/7)/(1/2)=
(-3/7)*(2/1)=-6/7
Step-by-step explanation:
2×9n=18n
2×-6=-12
52-12+18n= 38 +18n
2×7n=14n
8×2=16
14n+16
38+18n=14n+16
subtract 14n from 14n and 18n
38+4n=16
subtract 38 from 38 and 16
4n=-22
divide each side by 4
n= -5.5
Using the exponential growth principle, the population of the country in the next 50 years would be 8074764.08722
<u>The</u><u> </u><u>exponential</u><u> </u><u>growth</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>modeled</u><u> </u><u>using</u><u> </u><u>the</u><u> </u><u>relation</u><u> </u><u>:</u>
- <em>A</em><em> </em><em>=</em><em> </em><em>initial</em><em> </em><em>population</em><em> </em><em>value</em><em> </em><em>=</em><em> </em><em>3,000,000</em>
- <em>r</em><em> </em><em>=</em><em> </em><em>growth</em><em> </em><em>rate</em><em> </em><em>=</em><em> </em><em>0.02</em><em> </em>
- <em>t</em><em> </em><em>=</em><em> </em><em>time</em><em> </em><em>=</em><em> </em><em>50</em><em> </em><em>years</em><em> </em>
<u>Substituting</u><u> </u><u>the</u><u> </u><u>values</u><u> </u><u>into</u><u> </u><u>the</u><u> </u><u>equation</u><u>,</u><u> </u><u>we'll</u><u> </u><u>have</u><u> </u><u>:</u><u> </u>
= 8074764.08722
Therefore, the population in the next 50 years would be 8074764.08722

Answer:
x = -3, y = 5
Step-by-step explanation:
first, take the 3x + 17 = y and put it in place for the y in the second equation.
-3x=4x+17+4
then, solve the equation.
-3x=4x+21
-3x-4x=4x-4x+21
-7x=21
-7/-7x=21/-7
x = -3
substitute in other equation
4(-3) + 17 = y
-12 + 17 = y
y = 5
answers are x = -3 and y = 5
<span>Three- toed sloths move very slowly, using as little energy as possible. They sleep, eat, and even give birth upside down.
A three-toes sloth usually sleeps 101 hours per week.
Since the baby sloth clings to its mum for 36 weeks and we know that it sleeps 101 hours per week, therefore, we can simply calculate the duration of its sleep as follows:
duration of baby sloth's sleep in 36 weeks = 36 x 101 = 3636 hours</span>
