What is the answer for -4(m+3)=24

ale4655 [162]

Hello from MrBillDoesMath!

Answer: m = -9

Discussion:

Divide both sides by -4:

(m+3) = (24/-4) = -6 or

m+3 = -6

Subtract 3 from both sides:

m + 3 - 3= -6 -3 or

m = -9

Thank you,

A newly constructed fish pond contains 3000 liters of water. Unfortunately the pond has been contaminated with 5 kg of a toxic c

Paraphin [41]

Answer:

$\frac{dm}{dt}=-\frac{m}{30}$

Step-by-step explanation:

We are given that

Volume of water in fish pond,V=3000 L

Mass of toxic chemical=5 kg

Rate=200L/min

Removes chemical=50%

We have to find the differential equation for the time.

Let mass of toxic at any time t= m kg

Rate=Rate in-Rate out

$\frac{dm}{dt}=200\times 0-\frac{m}{3000}\times 200\times \frac{50}{100}$

$\frac{dm}{dt}=0-\frac{m}{30}$

$\frac{dm}{dt}=-\frac{m}{30}$
