If he ate 1/3 of the pie and 8 pieces are left then 8 pieces = 2/3 of the pie and that means 4 pieces = 1/3 of the pie meaning 12 pieces = 3/3 of the pie so the pie was originally cut into 12 pieces.

when we are finding Z we can use the information in the question \(z^3+14=-74+ci\) and we find out that \(z = \sqrt[3]{ci-88}\)

We know that there are 8 items in 1 set and he sold 112 items so... our equation is 112/8 = 14 and we know each set sold 2 pens so... 14*2 = 28 pens sold altogether.

ahhhh.......my bad 
multiply 5 instead so you would get -35 *5 and get -175 so

-175 = v

It took Kathy 13.1 sec 

and 3 racers finished faster than 14 sec and there are 11 racers not including Kathy so if you're including her the fraction would be 1/4 not including her would be 3/11

well, the first-place finisher had a time of 12.7 and the last place finisher had a time of 16.3 so... 16.3 - 12.7 is 3.6 

the first place was 12.7 
second place was12.9 
third place was also 12.9
fourth place was 13.2 
so we just add all of them up and get 51.7

lol... I was about to say I thought I did something wrong

-43 = v/5 - 8 
                      add 8 on both sides
-35 = v/5 
                      divide 5 on both sides
-35/5 = v
                      divide
-7 = v

this is a bit easier 

5 + 2u = -1
                  subtract 5 on both sides
2u = -6
                  divide 2 on both sides
u = -6/2
                  divide
u = -3

Guest, you were soooo close!!!!

so..... let me explain

6 = -4 + 5y 
                      add for on both sides
10 = 5y
                     divide 5 on both sides
10/5 = y
                    divide
2 = y

Okay this was a little bit hard doing in my head but if you have graph paper it comes in handy so I drew the coordinate plane and then just plot your points and you see point A is +8 apart from the midpoint (m) so knowing that point B is going to be -8 away from the midpoint which then makes the x coordinate of point B (-13,y) and then your Y would be the same as you point A so B = (-13,4)
