Hey, TailsIsTheBest!
Great question=)

Question:<span>What is the value of the expression f2 + 8 if f = 7?

Answer:22

Work:They already gave us the value of the variable f, so all we have to do it plug in 7 for f's place. 

(7)2+8
7*2=14
14+8=22

I hope this helps;)
If you have any questions on my work, feel free to ask me.

If the values are placed right next to each other without a symbol, then you multiply them. 
So, you multiply the value of 7 with 2, since they are placed right next to each other. 
(7x2) + 8 = 14 + 8 = 22

Answer:

You asked to solve questions 3 and 5

<h3>#3</h3>

Since CD = EF,

  • 9x - 1 = 41 - 5x
  • 9x + 5x = 41 + 2
  • 14x = 42
  • x = 3
  • EF = 41 - 5*3
  • EF = 26
<h3>#5</h3>

MN = NP as their perpendicular bisectors are of same length.

  • 9x - 43 = 5x + 33
  • 9x - 5x = 33 + 43
  • 4x = 76
  • x = 19
  • mMP = 360 - (mMN + mNP)
  • mMP = 360 - (9*19 - 43 + 5*19 + 33)
  • mMP = 104

There is a bag filled with 4 blue and 5 red marbles.
gavmur [86]

1) first pick red 5/9 blue 4/9


2) second pick when red has been picked red now becomes 4/8, blue stays 4/8


2) Second pick when blue has been picked blue now becomes 3/8, red stays 5/8


Mind you, you only need both different colours so:

first pick red 5/9 x sec pick blue 4/8 = 20/72

and first pick blue 4/9 x sec pick red 5/8 = 20/72

add both up 20/72 + 20/72 = 40/72 = 5/9
