Answer:

x = 15 and y = 7

Step-by-step explanation:

x = 2y + 1

x + y - 8 = 14

Let's substitute the value of x in the second equation:

(2y + 1) + y - 8 = 14

3y -7 = 14

3y = 14 + 7

3y = 21

y = 21/3

y = 7

And now you substitute the value of y in the first equation:

x = 2•7 + 1

x = 14 + 1

x = 15

Answer is too right
You know the y intercept is -4 so it’s gotta be on of the top 2. Then I plugged in x=1 and it’s just shy of 6 for the one in the top right which matches the graph.

Answer:

The equal number of books that is arranged on 16 empty shelves is 36 .

Step-by-step explanation:

Given as :

The total number of books Miguel need to arrange = 576

The total number of empty shelves = 16

Let The total number of books arrange on each shelves = x

So , According to question

The total number of books Miguel need to arrange = The total number of empty shelves × The total number of books arrange on each shelves

I.e 576 = 16 × x

Or, x = $\frac{576}{16}$

∴ x = 36

Hence The equal number of books that is arranged on 16 empty shelves is 36 . Answer

PLEASE HELP! THANKS!

If you add everything up then
14x-2=180
14x=182
x= 13

So the angles would equal
2(13)+1= 27
3(13)-3= 36
9(13)= 117
The angles are 27 36 and 117
Which makes the smallest angle 27 which is B.

Answer:

It takes the second worker 11 hours to do the job alone

Step-by-step explanation:

The problem tells you how to work it.

$\dfrac{1}{11}+\dfrac{1}{x}=\dfrac{2}{11}\\\\x+11=2x \qquad\text{multiply by 11x}\\\\11=x \qquad\text{subtract x}$

x = 11 tells you the second worker takes 11 hours to do the job alone.

_____

You can also work directly with the fractions. Subtract 1/11 and you have ...

1/x = 1/11

It should not be a real stretch to see that x=11. If you need, you can multiply both sides by 11x to get 11=x.
