Answer:

1. x+y=16 (the y’s cancel because they are inverse operation)

  x-y=10 (x+x=2x and 16+10=26 now the equation is 2x=26 now just solve for x by dividing 2 on both sides 26/2=13)

YOUR NOT DONE YET: (Now that we've found x let's plug it back in to solve for y.Write down an original equation I’m using x+y=16 And Substitute 13 for x)

the equation is 13+y=16 now subtract 13 on both sides and you should get y=3

2. for number 2 it’s the same as number 1

3. in this one the x will cancel each other because they are inverse)

(for the rest please use the website: Mathpapa it’s very helpful I would do more but I’m running out of time hopefully you can use this as a example to do the rest I’m really sorry I couldn’t do the rest)

An athlete runs around a circular track. The track has a diameter of 200 feet. How many laps does she need to take to run a mile
Shtirlitz [24]
First you have to figure out the length of the track:

2 * \pi * r

r is the half of the diameter:
200ft : 2 = 100ft

2* \pi *100ft = 200\pi≈ 628,31

The athlete has to run ca. 5280ft for one mile:

5280 : 628,31≈8,4

The athlete has to run 8,4 laps

Solve the system of equations.<br><br>- 9x + 4y = 6<br><br>9x + 5y = -33​
liubo4ka [24]

Let us solve this system of equations by using the elimination method. Adding the 2 equations, we get

9x + 5y - 9x + 4y = -33 + 6

9y = -27

y = -3

Substituting this value of y in the first equation, we get

-9x + 4(-3) = 6

-9x - 12 = 6

9x + 12 = -6

9x = -18

x = -2

Therefore, x = -2, and y = -3. Hope this helps! If you have any questions, feel free to ask.
