Answer 2

\[\huge\color{red}{6x-24=(5+2x+7)\frac{1}{2}}\]\[\huge\color{red}{6x-24=x+6}\]\[\huge\color{red}{6x-x=6+24}\]\[\huge\color{red}{5x=30}\]\[\huge\color{red}{x=6}\]

Answer 4

okay thanks your really kind

Answer 5

Anytime, guys!

Answer 6

Can you do this? @SolomonZelman And yeah you don't send anyone money! This website is for helping. :D ( and for free)

Answer 7

i know its alot of questions but its cause my math teacher left us a sub and now she wants us to take this final and i dont understand any of it.

Answer 8

Ok, but please post one question per thread, i can try to help you.

Answer 9

okay sorry its been a while since ive used this website sorry.

Answer 11

I am really sorry, but can you post the question here, in a thread, so that I won;t have to look here and back into the attachment please?

Answer 12

What is the length of the midsegment of the trapezoid made by the vertices A(0,5)B(3,3)C(5,-2) and D(-1,2). Show equations and all work that lead up to your answer.

Answer 13

um ok its alot so ill only as you two so your not overwhelmed@solomanzelman

Answer 14

@SolomonZelman

Answer 15

just an advice @Hello_Im_Nick for these types of question which u asked just follow BIMDAS rule then it will be easy for u.

Answer 16

What's BIMDAS?

Answer 17

Bracket, Index, Multiplication, Division, Addition and subtraction.

Answer 18

so u solve ur equation in order of this.

Answer 19

But can you help me solve this one? please show your steps. I want to do the next one by myself.

Answer 20

@SolomonZelman i have this final and for the passed week we had a sub and i dont understand anything if someone is willing to help me even though its alot of questions i am willing to mail anyone five dollars for helping me i would offer more but thats all i have? my first question is 2x+3y+3z=5 4x+5y+3z=13 using matrices A.(5,13,13) B. (2,4,3) C. (1,2,-1)
D. (1,3,-2) my second question is given the hyperbola (x2/4)-(y^2/9)=1,find asymptotes. A. x=(1/3)y,x=(-1/13)y B.y=(1/3)x,y=(-1/3)x C.y=(3/2)x,y+(-3/2)x D.x=(3/2)y,x=(-3/2)y

Answer 22

you dont have to help with all

Answer 23

do you mean use of substitution method to solve the system of linear equations, I can teach you if you want to.

Answer 24

it asks for elimination for the first question idk how to do that

Answer 25

really u dont know elimination method do u want me to show u an example.

Answer 26

sure hopefully ill understand

Answer 27

Can you guys help me as well....

Answer 28

Solve the system of equations by elimination
3x-y=5
x-y=3
In this example we will "cancel out" the y term. To do so, we can add the equations together.

3x-y=5
x-y=3 (add equation)
4x=8
Now we can find: x = 2

In order to solve for y, take the value for x and substitute it back into either one of the original equations.
x+y=3
2+y=3
y=1
The solution is (x, y) = (2, 1).

Answer 29

But whats the length of the midsegment?
