Answer: $\frac{3}{8}x-\frac{41}{5}$ or $\frac{3}{8}x-8\ \frac{1}{5}$

Step-by-step explanation:

Given the following expression:

$\frac{3}{4}(\frac{1}{2}x-12)+\frac{4}{5}$

You can follow these steps in order to simplify it:

1. You need to apply Distributive property:

$=\frac{3}{8}x-9+\frac{4}{5}$

2. And now you must add the like terms. Then:

$=\frac{3}{8}x-\frac{41}{5}$

Therefore you get the following answer:

$\frac{3}{8}x-\frac{41}{5}$ or $\frac{3}{8}x-8\ \frac{1}{5}$

Y=6x-1, y=3x-4 the solution is_____

TEA [102]

Answer:

y= -7 and x= -1

Step-by-step explanation:

To do this, line up the variables so it looks like this...

y-6x=-1

y-3x=-4

The reason why -6x and -3y changes to negative is because that it moved to the other side of the equation.

distribute negative to the bottom equation because the two equations have the same number variable which is y...

y-6x=-1

-y+3x=4

Y cancels out and it will be left with -3x = 3.

X = -1.... plug that in to any of the two equation and you get y = -7.

Hope I helped and have a nice day!!

The Florida Fish and Wildlife Conversation Commission (FWC) plans to hire hunters to kill the Burmese python, an invasive specie

andrew-mc [135]

Complete Question

The complete question is shown on the first uploaded image

Answer:

FWOC should hire 70,000 hunters to completely remove the python in the area

Step-by-step explanation:

From the question we are given that the Initial Pythons $P_o=$ 100,000

And the final python $P_f$ $=100,000+\frac{P}{10,000}(100,000-P)$

$P_f = 100,000 + 10P -\frac{P^2}{10,000}$

For Max Number of Python

=> $\frac{dP_f}{dP} = 0$

=> $\frac{dP_f}{dP} =$ $100,000 -2P = 0$

=> $P = 50,000$

Hence the maximum number of pythons $Max_P$ $=100,000 +\frac{50,000}{10,000} (50,000)$

$=350,000$

Using Mathematical relations

from the Question

5 python is killed by = 1 hunter

1 python is killed by = $\frac{1}{5} \ hunters$

350 , 000 pythons are killed by = $\frac{350,000}{5}$

$= 70,000 \ hunters$
