Answer:
(p+e)/(r-n) = x
Step-by-step explanation:
p + nx=rx-e
Add e to each side
p +e+ nx=rx-e+e
p +e+ nx=rx
Subtract nx from each side
p +e+ nx - nx=rx-nx
p+e = rx -nx
Factor out x
p+e = x(r-n)
Divide each side by (r-n)
(p+e)/(r-n) = x(r-n)/(r-n)
(p+e)/(r-n) = x
Answer:
If both sides are equal
Step-by-step explanation:
If both sides are equal and are the same in both sides of the equation, than it is a solution.
For instance, the solution for 2x = 4, is x = 2 because 2(2) = 4 is 4 = 4.
Answer:
Step-by-step explanation:
the graph correspond to the function f :
Probability that the first captain's first pick is a girl = 11/21
Probability that the first captain's second pick is a girl = 12/25
<span>the probability that the first captain will pick two girls before picking any boys = 11/21 x 12/25 = 132/525 = 44/175</span>
