LUCKY_DIMON [66]

Answer:

A=60, B=80, and C=67

Step by step explanation:

B= 2a

C= a+27

With the information, you get the equation:

A+A+27+2A=187

Then, you have to simplify.

You then get 4a+27=187.

Now, you subtract 27 from both sides to get: 4a=60.

Divide both sides by 4 to get A= 60.

If A=60, 2A=80, so B=80. A+27=67, so C=67.

You check this by adding them up to see if they equal to 187, which in fact, they do.

A=60, B=80, and C=67.

Hope this helped!

A population of 400 beetles grows by 5% each week. How can the beetle population be determined after a number of weeks, w?
patriot [66]
*5% in decimal form is 0.05.

After one week we have:
N=400*1.05 beetles

After two weeks we have:
N=(400*1.05)*1.05 beetles

After three weeks we have:
N=((400*1.05)*1.05)*1.05 beetles

We can write this as:
Week 1:
N=400* 1.05^{1}
Week 2:
N=400* 1.05^{2}
Week 3:
N=400* 1.05^{3}

From this we can make conclusion that formula for number of beetles after w weeks is given by:
N=400* 1.05^{w}
