2w-1 divided by 5+w+2=2w

Mathematics

Answer:

(2w-1)/5+w+2=2w

We simplify the equation to the form, which is simple to understand  

(2w-1)/5+w+2=2w

Reorder the terms in parentheses

( + 0.4w-0.2)+w+2=2w

Remove unnecessary parentheses

+ 0.4w-0.2+w+2=2w

We move all terms containing w to the left and all other terms to the right.  

+ 0.4w+1w-2w=0.2-2

We simplify left and right side of the equation.  

-0.6w=-1.8

We divide both sides of the equation by -0.6 to get w.  

w=3

is the sum of two polynomials of degree 5 always a polynomial of degree 5? Give an example to explain your answer
ddd [48]
A counter example is

f(x)=5x^5+2x^3+3x
g(x)=-5x^5-x^4+x^2-4

Then f(x)+g(x) = -x^4+2x^3+x^2+3x-4  which is a polynomial of degree 4.

So the answer is no.  Counter-example is given above.

Write two decimals one repeating and one terminating with values between 0 and 1 then write an inequality that shows the relatio
LuckyWell [14K]
This is a fairly easy question. So I'll break it down and give you a description of the terms.

A repeating decimal (like 1/3, 3.333etc is often written as 3.3 with a dot above the second 3 or a ... or an etc) can be anything you chose, 0.7222etc...., 0.3555etc.... Any number which goes on forever. Your choice! A terminating decimal does not go on forever, like 0.25 or 0.43353. It can be as long as you like but it has to end at some point. 


Inequalities are just a question, which value is bigger? You use a < or > to show the relationship, x<y means x is smaller than y. Same for y>x.

So just choose two numbers, 0.333... and... let's say, 0.72. 0.72 is larger so we write 0.333...<0.72

Done!

What's the total Cents?
saveliy_v [14]

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

Answer:

Let's see...

Step-by-step explanation:

  • The first coin is a quarter.
  • The second, third, fourth, and fifth coins are dimes.
  • The sixth, seventh, and eighth coins are nickels.

That being said, what is the total value of the cents?

cents    =  ¢

<u>Values:</u>

Quarter = 25 ¢

Dime     = 10 ¢

Nickel   = 5 ¢

So,

1 quarter + 4 dimes + 3 nickels    = total cents

25 + 10 + 10 + 10 + 10 + 5 + 5 + 5 = total cents

25 + 40 + 5 + 5 + 5                       = total cents

25 + 40 + 15                                  = total cents

25 + 55                                         = total cents

80                                                  = total cents

<h3><em>Our answer is 80¢</em></h3><h3><em /></h3>

I hope this helps!

Need help ASAP! due soon!!!
-BARSIC- [3]

Answer:

Option B

Step-by-step explanation:

First make x = 4 and y = 3 in the equation y = -1/2x + 5

it should look like 3 = -1/2(4) + 5 now we can solve

   -1/2 * 4 = -2         →      3 = -2 +5

       -2 + 5 = 3         →          3 = 3
