-3 - x = -2w + 4v, for x

Mathematics
1 answer:
Aneli [31]3 years ago

Hi there!

We have:

-3 - x = -2w + 4v

Solve for x

Start by adding 3 to both sides

-3 - x + 3 = -2w + 4v + 3

-x = -2w + 4v + 3

Remember that we cannot leave the  x with a negative sign.

There are two ways to remove the negative sign.
1) We can divide both sides by -1
2) We can multiply both sides by -1

In this, I am going to multiply both sides by -1

-x * -1 = (-2w + 4v + 3)(-1)

x = 2w - 4v - 3


I hope this helps.

Please let me know if you have questions about the answer.

Thanks!

What is (2y + 14.6m + 3.8) – (34.8m + 15.6 + 2y)
zhenek [66]

Answer:

-20.2m -11.8

Step-by-step explanation:

(2y + 14.6m + 3.8) – (34.8m + 15.6 + 2y)

Distribute the minus sign

(2y + 14.6m + 3.8) – 34.8m - 15.6 - 2y

I like to line them up vertically

   2y + 14.6m + 3.8

– 2y   -34.8m - 15.6

------------------------------

       -20.2m -11.8

Which graph shows the solution to the following inequality?<br>4d- 6 &lt; 18 <br>PLEASE HELP​
kenny6666 [7]

Answer:

answer a

Step-by-step explanation:

4d-6 < 18

  • Let's isolate d on one side of the equation. Ignore the inequality for now. We'll deal with that later.

4d-6=18\\4d-6+6=18+6\\4d=24\\\frac{4d}{4}=\frac{24}{4}\\ d=6

  • Now, I'm going to bring back the inequality or < symbol. I only removed it when simplifying and isolating d, but if this confuses you, just do your math and keep the inequality there.

d < 6

  • On a number line, this would include every number <em>less than </em>6, due to the < (less than) symbol. This disqualifies answers b and d because they are showing every number <em>greater than </em>6. But, how do we decide between answers a and c?
  • If a line has point at its beginning, 6, then that means that every number <em>less than or equal to</em> [ ≤ ] 6 is being shown, but our equation just says <em>less than </em>[ < ] 6, so answer a is our correct answer.

How do you convert 250% into a fraction
Ann [662]
Hello there.

Question: <span>How do you convert 250% into a fraction.

Answer: </span>Step 1: Factor both the numerator and denominator down to prime factors:
250 = 2 * 53 
100 = 22 * 52
Step 2: Calculate the greatest common factor, GCF 
GCF = (2 * 53; 22 * 52) = 2 * 52 
Step 3: Divide both the numerator and denominator by their greatest common factor, 250/100 =
(2 * 53)/(22 * 52) = 
<span>((2 * 53) : (2 * 52))</span> / <span>((22 * 52) : (2 * 52))</span> =
5/2
Ways of writing this:

<span>Positive improper fraction: 
250/100 = 5/2 

Mixed number (also called mixed fraction): 
250/100 = 2 1/2 

Decimal number: 
250/100 = 2.5

In short, Your answer is<span> 5/2</span>.

Hope This Helps You!
<span>Good Luck Studying ^-^</span></span>

Ilya [14]

Answer:

B.

Step-by-step explanation:

Since 6 = 5r + 1, r = 1

As for s, if s is 2, then you can do

4 x 2 + 5 = 13 & 6 x 2 + 1 = 13

13 = 13

So B!

Hope that helps!
