Circles M and K are congruent, arc QR is congruent to arc LN and arc OP is congruent to arc VW. Find x.
SCORPION-xisa [38]

Given, arc QR is congruent to arc LN and arc OP is congruent to arc VW.

And the expressions for each arc in the diagram also given as:

Arc QR = 2x - y, arc LN = 11 , arc OP= 10 and arc VW=5x+y.

Hence, we will get the system of equations as following:

Arc QR = Arc LN

2x - y = 11 ...(1)

Arc OP = Arc VW

5x + y = 10 ...(2)

We need to find the value of x. So, we can add the equations to eliminate y so that we can solve the equations for x. Therefore,

2x+5x = 11 + 10

7x = 21

\frac{7x}{7} =\frac{21}{7} Divide each sides by 7.

So, x= 3

Please show your work! I have 3 more of these, and I want to be able to do them by myself.
Radda [10]

Answer:

Step-by-step explanation:

We group the number 5:

5(x² + 3x + 2.25)

Now inside the brackets we'll take the square root of the coefficient of the x and the square root of the last number, then remove the square from the x and write it as a sum:

5(x+1.5)²

What's the idea behind this?

Well, remember that when you have something in the form:

(a+b)²

It actually means:

a² + 2ab + b²

In our case a was x, and b was 2.25. For bringing it into the shorter form we have to take the square root of a and b.

Sorry if you don't understand. Tell me if you need help to get the xoncept better.

Find the quotient and the remainder: (x^2+3x-4)/(x-1)
skelet666 [1.2K]
Evaluate this...
\frac{x^2+3x-4}{x-1}
the x at the bottom cancels out one of the xs at the top so it will be
\frac{x^2+2x-4}{-1}
Now the one cancels out one of the 1s in the -4 so
{x^2+2x-3}

Hope this helps :)

Percent change from 45 to 56
makkiz [27]

The percentage of change from 45 to 56 is 24.4%

To find this, we first need to find the difference between our two values. This difference would be 11.

The next step would be to divide 11 by 45. We then move the decimal point over two spots to the right which gives us our answer.
