Answer:k/22 =-66
k=-1,452
Step-by-step explanation:
There is a total of 66 socks on the floor the chance of picking up a red sock is 30 in 66 which is equal to a 45% chance. After picking up one sock the chances of getting another red sock is 29 in 65 which is around 44%. Now I believe your answer is 45% or around 30 socks. I hope this helped but please let me know.
Xy=10
x+y=29
subtract x from both sides for second equation
y=-x-29
subsitute in second equaiton
x(-x-29)=10
-x^2-29x=10
add x^2+29x to both sides
x^2+29x+10=0
quadratic formula
if you have
ax^2+bx+c=0,
x=
so
x^2+29x+10=0
a=1
b=29
c=10
x=
x=
x=
x=
x=
or
those are the 2 numbers
aprox=-28.65 and -0.349
