3x + 6y= 180What is x and y​

Mathematics
1 answer:
Diano4ka-milaya [45]3 years ago
3 0

Answer and explanation:

<h2>X</h2>

3x + 6y = 180  <em>Use the original expression to find x</em>

3x = 180 - 6y  <em>Subtract 6y by both sides</em>

\frac{3x}{3} = \frac{180}{3} - \frac{6y}{3}  <em>Divide by 3 to get x</em>

x = 60 - 3y

<h2>Y</h2>

x = 60 - 3y  <em>Use the new expression to find y</em>

x - 60 = - 3y  <em>Subtract 60 by both sides</em>

\frac{x - 60}{-3} = \frac{-3y}{-3}  <em>Divide by -3 to get y</em>

-\frac{x}{3} + 20 = y

The population of a colony of mosquitoes obeys the law of uninhibited growth. If there are 1000 mosquitoes initially and there a
Anettt [7]

Answer:

1) The size of the colony after 4 ​days is 6553 mosquitoes

2) After t = 4.9\ days

Step-by-step explanation:

To answer this question you must use the growth formula

N = N_0e ^ {kt}

Where

N_0 is the initial population of mosquitoes = 1000

t is the time in days

k is the growth rate

N is the population according to the number of days

We know that when t = 1 and N_0=1000 then N = 1600

Then we use these values to find k.

1600 = 1000e ^{k(1)}\\\\\frac{1600}{1000} = e ^ k\\\\ln(\frac{1600}{1000}) = k\\\\k = 0.47

Now that we know k we can find the size of the colony after 4 days.

N = 1000e ^ {0.47(4)}\\\\N = 6553\ mosquitoes

To know how long it should take for the population to reach 10,000 mosquitoes we must do N = 10000 and solve for t.

10000 = 1000e ^ {0.47t}\\\\10 = e ^ {0.47t}\\\\ln(10) = 0.47t\\\\t = \frac{ln(10)}{0.47}\\\\t = 4.9\ days
