+ 252

Yeah I might post more of those up, they are in a bio I have for math class 

I am sure you will get it!

Just focus, and keep trying.

Wow! I have keep reading that over till I know how to do it!

10m – 2 = 9m – 14

Subtract 9m from both sides.

10m - 9m – 2 = 9m - 9m – 14

Solve.

m - 2 = (-14)

Add 2 to both sides. (Do the opposite of the sign it shows. Negative = Positive. Times = Divide)

m - 2 + 2 = (-14) + 2

Solve.

m = (-12)

Always make sure m positive. 

It's actually very helpful for life, you may not see it now, but in the future you will most definitely need it, like to get a job because most jobs require math skills 

I will show you!

What if it has 4 numbers like this : 10m – 2 = 9m – 14

Sure!

-19y = -15 – 16y

First, add 16y to the left side and the right side.

-19y + 16y = -15 - 16y + 16y

This cancels out - 16y from the left, making it easier to solve.

-3y = -15y

Change both signs to a positive (Only if both sides are negative or already positive)

3y = 15

Divide by 3 on both sides.

3y/3 = 15/3

Solve.

y = 5

When you divide 3y by 3, it cancels out the three, because 3/3 is 1, and 1y = y.

So your answer is y = 5

8x2/3

8x2 = 16

16/3 = 5.33333

OR

5 1/3

7n - 5n – 18 = 14 + 5n - 5n

2n - 18 + 18 = 14 + 18

2n/2 = 32/2

n = 16

Yeah, nice, 

Really? I learned this just last week, I am in Algebra 1 in 7th Grade =P

I've been put in grade 11 math when I'm not supposed to be in it 

You're welcome! 

TYSM!!!!!

6u + 15 = 11u

-6u          -6u

15/5 = 5u/5

3 = u

It is a color

thought they said a de@r got hit by carl

Call the angle LNB $\displaystyle \theta$ (I resist using the word measure !), then LRB will be $\displaystyle \theta/2.$

Call the angle RND (RNO ?) $\displaystyle \phi$, then RBD (RBO ?) will be $\displaystyle \phi/2.$

etc..

cos(a*b)=?

Uhh, dont get me wrong, but i think this is not his birthday

https://web2.0calc.com/questions/its-my-birthday-in-two-days-sept-25#r5

And he's not 19 he's 13

Thanks guest 

That is what I thought too but I don't like the terminology much.

What was wrong with how we did it in the old days. Lol

I still don't know how to answer the question though :((
