Answer:
Step-by-step explanation:
a)
As given y=mx lets replace mx with y in the first equation
2y=n => y=n/2, replace y with n/2 => mx=n/2, thus x=n/2m
b)
As given y=nx lets replace y with nx in the first equation
x+n^2x=m => x(n^2+1)=m = > x=m/(n^2+1), thus y= n*m/(n^2+1)
c) Replace y with nx => mx-nx=n => x(m-n)=n = > x=n/(m-n), thus y=n^2/(m-n)
He has 9 choices for the first role, and that leaves him 8 people to choose for the second so he has 9*8 = 72 choices for the first two roles; that leaves 7 possible choices for the third role so that gives him 9*8*7 choices or 504 different ways he can assign the roles. i think this is correct.
Do 4x-10 +5x-22+3x+2=180 to find what x equals
I think you meant 'x + 4x = -2'
Combine like terms:
5x = -2
Divide 5 to both sides:
x = -2/5 or -0.4
<span>Product means, the answer of numbers being multiplied with
each other.
In the given situation, we need to find three numbers that will be multiplied
with each other to get a product which is 9000.</span>
<span>Now, let’s find the possible numbers to be multiplied:
=> 300 X 30 X 1
=> 9000 x 1
=> 9000
Or this one also applies:
=> 4500 x 2 x 1
=> 9000 x 1
=> 9000</span>
There are a lot of ways to get a product of 9000 by multiplying
3 digits.
