Hello!
You can make two expressions based on what you know
let x equal the larger number
let y equal the smaller number
x + y = 95
x + 2y = 120
We can use elimination to get rid of x
You can subtract the two equation to get rid of x
-y = -25
Since y is negative we can multiply both sides by -1 to make y positive
y = 25
Now we can put this into one of the other equations to find x
x + 25 = 95
subtract 95 from both sides
x = 70
The answers are 70 and 25
Hope this helps!

You need one equation for the physical nickels and dimes, which total to 21:
n+d=21
Secondly, you need one equation for the numerical value of those nickels and dimes. We know nickels are worth $0.05 and dime are worth $0.10:
.05n+.1d=1.70

Answer:
The probability that the proportion of the core being used at any particular time will be less than 0.10 is 0.08146
Step-by-step explanation:
1/3 0.33 = 33.33 %
The Probability of that the proportion of the core being used at any particular time will be less than 0.10 is given by
PDF =
where x = 0.1
α = 2 and β = 4
PDF = = 1.458
CDF = = 0.08146
The probability that the proportion of the core being used at any particular time will be less than 0.10 = 0.08146.
