If the pencil markings are correct, LM=NP.
This means that both lines should be the same length (you've marked them as congruent). Therefore, you can set the two equations equal to one another.
3x=5x-14
You should get a solution of x=7. If you have trouble with that, comment. I was lazy and did it with my graphing calculator, but I can show you how to do it algebraically.

From the drawing, assuming your congruency markings are correct, K is the midpoint of LM. Therefore, LK will be half the length of LM.
As LM looks like it equals 3x, LK would be 3x/2. In the above step, I found that x=7. Plug x unto the equation 3x/2 to get 21/2, which is your final answer.

Get a common denominator of 15

1/3*5/5 = 5/15

4/5*3/3 = 12/15

5/15 - 12/15

Please help me find the value of this expression 2[5(11 - 2)] - 16
german
Hello there, and thank you for asking your question here on brainly.

Short answer: 74

Why?

We have two sets of parenthesis here, and we have to do the parenthesis inside of the other parenthesis, (called brackets) first. (11 - 2 = 9) Now multiply 9 by 5. (9 × 5 = 45) Multiply 45 by 2 . . . (45 × 2 = 90) Finally, subtract 90 by 16. (90 - 16 = 74)

Hope this helped you! ♥

egoroff_w [7]

Answer:

system 4.

Step-by-step explanation:

3x+6y=9

multiply by 2

6x+12y=18   ....(1)

-2x+-4y=4

multiply by 3

-6x-12y=12   ...(2)

add (1) and (2)

0+0=30

which is impossible .It has no solutions.

A torch and a battery cost £2.50 altogether. The torch costs £2.00 more than the battery.
Hitman42 [59]

Answer:

1/5

Step-by-step explanation:

To find what fraction of the total price the battery is, we need to find out how much the battery alone is first.

Since the battery and torch together are £2.50 and the torch is £2.00, we can find the price of the battery by subtracting the total price to the price of the torch.

Battery Price = £2.50 - £2.00

Battery Price = £0.50

The fraction value of the torch is:

2.00 of 2.50 = 4/5

That then leaves us with:

0.50 of 2.50 = 1/5

To check we need to add the two fractions together.

1/5 + 4/5 = 5/5 or 1
