In mathematics, mean average means to take the sum of all the numbers and divide the sum by the number of elements in the set.

Add up the numbers.

<span>21 + 23 + 25 + 25 + 26 + 28 + 28 + 28 + 31 + 33 = 268

Divide by the number of elements in the set. Which is 10.

268 / 10 = 26.8

So, the answer to this question is 26.8</span>

448 = -5v + 8(-5 - 7v)<br> What is v?
lapo4ka [179]

Answer:

v = -8

Step-by-step explanation:

First we would have to distribute the 8(-5 - 7v). To do this we would multiply 8 by -5 and 8 by -7v to get 448=-5v-40-56v. After this, we would have to simplify like terms by subtracting 56v from -5v to get 448=-61v-40. We now have to get the variable on one side and to do that, we can add 40 to both sides to get 488=-61v. Finally to get the variable alone, we would have to divide both sides by -61 to get v=-8.

Brainliest would be appreciated!

Use the simple interest formula to find the ending balance 5000 at 5% for 3.5 years
Evgesh-ka [11]

Answer:

Given:  Principal(P) = $ 5000 , T = 3.5 years and R = 5%.

Using the formula of Simple Interest (I) given by;

I = \frac{P\times R \times T}{100} .......[1] , where P is the Principal amount of money to be invested, R be the rate of interest and T be the time.

Substitute the given values of P ,  R and T in [1] we have;

I = \frac{P \times R \times T}{100} = \frac{5000\times 5 \times 3.5}{100}

I = 50 \times 5 \times 3.5 = 250 \times 3.5

Simplify:

I = \$ 175

An Ending balance is calculated by subtracting cash outflows, interest paid for financing and principal paid on financing.

Ending Balance = $ 5000 + $ 175 = $ 5,175.

Therefore, the ending balance is $ 5,175

A Write an equivalent equation that does NOT contain decimals.
vampirchik [111]

                                                     <span>0.5x - 0.1 = -2.9

When you multiply each side of an equation by the same number,
you don't change the equation or its solution.  If you want to get rid
of the decimals, you could  multiply each side by  10.  Then the
equation is

                                                     5x - 1  =  -29

You should be able to solve that without help.
But I'm about to take your points, so here's
how to solve that equation:

                                            </span><span><span>5x - 1  =  -29

Add  1  to each side:        5x        =  -28

Divide each side by  5 :     x         =  -28 / 5

Simplify the solution:          x         =  -5 and 4/5 .

Again ... this is the same solution as the original equation
if we hadn't gotten rid of the decimals.
