Answer:
I think 1/2
Step-by-step explanation:
Since there are 4 coins overall and 2 nickels, then the probabilty is 2/4
2/4 simplified is 1/2
(I've never been too good at probability so sorry if it is wrong)
Why do you need the answer so bad? Are you trying to get a pet?
x=5
9x^2 - 2x + 25 = 8x^2 + 8x
9x^2-8x^2-2x-8x+25=0
x^2-6x+25=0 factorize
(x-5)(x-5)=0
x-5=0 then x=5
