Question

Find the value of x

Answer 1

okay

Answer 2

If I am correct, I think it should look like this: \[180=(5x+13)(3x+7)\] Then you would have to solve for x.

Answer 3

I will try the equation rn

Answer 4

Let me know what you get. There is an easier way of doing it if you want to know about it =)

Answer 5

I can't figure it out, can you help

Answer 6

ugh

Answer 7

No problem! Alright, so as you know a straight line is 180 degrees. If you look at your picture you can see that both the 5x+13 and the 3x+7. (See picture attached). So you know that both of them are equal to 180 degree. So you would set up the equation like I showed you above. Does this make sense to you?

Answer 8

yes

Answer 9

One easy way to do this is but the values into x and see if both of them add up to 180. For example: lest do 10. So: (5 times 10 + 13) + (3 times 10 +7) = 60 + 37 = 100. This does not equal to 180 so 10 is not the answer. So now I want you to do the same thing for the remaining options and tell me which one you think it is! =)

Answer 10

hmm..

Answer 11

give me a min

Answer 12

So its not 15 either..

Answer 13

15 went wayy over 180, but that meant any number higher than 15 would be to high as well

Answer 14

I'm not sure, Im so sorry. I suck at math a bunch

Answer 15

It's okay, the correct answer is 20. This is because 5 x 20 +13 = 113 and 3 x 20 + 7 = 67 and 112+67=180. So , the correct answer would be 20. =)

Answer 16

Ohh okay right. I really need to work on that. Im gonna try the other things you did also. And thank you so much you are a great help! :)

Answer 17

No problem! =)
