Question

can someone please help me solve a couple problems?

Answer 1

Sure. Just a tip, though; type your actual question into the question area so that people can answer it right away if they recognize the kind of problem you need to solve!

Answer 2

okay thank you, im doing geometry with some equations with shapes, i need to know how to solve y+12=6x?

Answer 3

Okay. By solving, do you mean graphing it?

Answer 4

here ill post the question

Answer 5

3. What is the value of y in LMNO ?

4
6
12
24

Answer 6

Is LMNO a parallelogram?

Answer 7

yes it is

Answer 8

Oh I see! If it is a parallelogram, then the diagonals bisect each other. So you can set up a system of equations:

y= 3x
y+12 = 6x

Can you go from there or do you want me to show you how to solve this system?

Answer 9

yes thats the equation i got, i need help solving it

Answer 10

You know that y = 3x. Substitute this fact into the other equation to get 3x + 12 = 6x. Now continue solving for x. Use the newfound value of x to get y.

Answer 11

Okay. Well if y is equal to 3x, you can just substitute it in the other equation.

Answer 12

Oh that's what @tyteen4a03 just said! Haha

Answer 13

@thechocoluver445 Taking turns :P

Answer 14

okay 3x+12=6x, how do i solve that? lol just work me through it

Answer 15

wait whatd you do with y?

Answer 16

Well if you subtract 3x from both sides, then you have 12 = 3x
So what is x?

Answer 17

You substituted it for 3x, since y = 3x, as established by the first equation.

Answer 18

okay x=4 so 3(4)=y, so y =12 ha thank you guys, i just needed a refresher, okay one more equation kinda similar to this can you help?

Answer 19

Haha good job! Sure

Answer 20

what is m<1 ?

20
60
80
100

Answer 21

Is this a parallelogram?

Answer 22

yes

Answer 23

Okay. Recall that if something is a parallelogram, then its opposite angles are congruent. So m<1 = 3m+20

And also, the adjacent (next to each other) angles are supplementary - this means they add up to 180. This is a fairly simple problem, you just set up an equation for one variable and solve.

So, if the adjacent angles add up to 180, that means that 3m+20 and 5m add up to 180. Can you come up with the equation that shows this?

Answer 24

yeah, 3m+20+5m=180? so then

8m+20=180
m=20

3(20)+20= m<1
m<1+80

Answer 25

i mean m<1=80

Answer 26

I think you mean to say m<1 = 80. That's right! :)

Answer 27

yes! thank you so much!

Answer 28

Np! Glad to help
