Then, the median is found by taking the mean (or average) of the two middle most numbers.
Let number of fives = x then number of ones = 3x and number of tens = x - 1
so we can create the equation
x + 3x + x-1 + y = 26 where y = number of twenties
so
5x + y = 27
also we have the equation
5x + 3x + 10(x - 1) + 20y = 120
18x + 20y = 130..................................(1)
5x + y = 27 multiply by -20:-
-100x - 20y = -540..............................(2)
Adding equation (1) and (2)
-82x = -410
x = 5, that is 5 fives
Now plug x = 5 into equation 1:-
18(5) + 20y = 130
20y = 40
y = 2 , that is 2 twenties
So the answer is there are (3x) = 15 ones , 5 fives, 4 tens and 2 twenties
Answer:
<h2>f(2) = - 12</h2>
Step-by-step explanation:
f(x) = x - 14
To find f(2) substitute the value of x that's 2 into f(x). That is for every x in f(x) replace it with 2
We have
f(2) = 2 - 14
We have the final answer as
<h3>f(2) = - 12</h3>

Answer: Hope this helps
Step-by-step explanation: Listen, exponents may be complicated at first but
The basic concept is to think of it like 2 to the 3rd power would be 2x2x2
since you are multiplying the number by itself three times
