How do you do this problem

Mathematics
1 answer:
Ainat [17]3 years ago

So the problem has no symbols, but we're going to multiply because the fraction on the left is right next to the parentheses. 

-5/2 * 1/10x = -5x/20

I put "x" next to the 5 because the "x" counts as part of the numerator. Now that it's 5x over 20 that equals one, I'd first reduce -5x/20 into -x/4, then do

-x/4 * -4 = 1 * -4

To make the "x" side equal one, we have to multiply both sides by -4, to make both sides equal. 

x = -4.

Solve the equation: <br> Two times n plus twenty-eight equals ninety-six.
just olya [345]

2n + 28 = 96 [Two times n plus twenty-eight equals ninety-six.}

You need to get n by itself, so you first subtract 28 on both sides

2n + 28 - 28 = 96 - 28

2n = 68    Divide 2 on both sides

n = 34

The area of a square is 49 square meters. How long is each side?
OLga [1]
Well if 49 is the area, and you get area by multiplying one side by another side, and its a square so the numbers are going to be the same, so you would be multiplying two of the same numbers. And two of the same numbers that equal 49 is 7.

There are approximately 3,000 bass in a lake. The population grows at a rate of 2% per year. Round answers to the nearest tenth.
Tamiku [17]

Answer:

years 1–4: 62.4 bass per year

years 5–8: 67.6 bass per year

Step-by-step explanation:

If the population in year n is ...

 p(n) = 3000·1.02^n

then the average rate of change from year 1 to year 4 is ...

 (p(4) -p(1))/(4 -1) = 3000(1.02^4 -1.02^1)/3 = 1020·(1.02^3 -1) ≈ 62.4

The average rate of change for years 1–4 is 62.4 bass per year.

For years 5–8, the rate of change is similarly computed:

 (p(8) -p(5))/(8 -5) = 3000(1.02^8 -1.02^5)/3 = 1000·1.02^5·(1.02^3 -1) ≈ 67.6

The average rate of change for years 5–8 is 67.6 bass per year.
