Help me....... c + 11=20;c=9

Mathematics

Blababa [14]4 years ago

Answer:


Step-by-step explanation:

If you are confused as to how the answer is 9 then all we have to do is solve for c

c + 11 = 20

So in order to solve this you have to subtract 11 from 20 to get c alone on one side so...

c = (20-11)

c = 9

All you have to do is add 9(or c) to the equation. If c is 9, then you just have to do 9 + 11 which would equal 20.

21) PLEASE HELP WITH QUESTION. WILL MARK BRAINLIEST + POINTS.
LenKa [72]
                             8
Suppose f(x) = ----------
                          sqrt(x) 
                                                                                                   8
What if we let x = 16 (just an example)?  We'd get f(16) = ------------- = 2.
                                                                                              sqrt(16)

What if we let x = g(x) = 2x+4?

We'd get the following:

                     8
f(g(x)) = -------------- = y
              sqrt(2x+4)

So...the correct answer is the fourth one.

The sum of one-fifth of a number and two is five
Veseljchak [2.6K]

Answer:

15

Step-by-step explanation:

Let us first write an equation where the unknown number is represented with variable x. <em>The sum of a fifth of x and two is five:</em>

\frac{1}{5} x+2=5

Great! Let's solve for x by isolating the variable.

\frac{1}{5}x=3\\x=15

<u>Therefore, the unknown number is 15.</u>

<u />

<em>I hope this helps! Let me know if you have any questions :)</em>
