Answer:
Barry ate 36 hot dogs.
Andy at 36+5 = 41 hot dogs.
Carl ate 36-10 = 26 hot dogs.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of hot dogs that Barry ate.
y is the number of hot dogs that Andy ate.
z is the number of hot dogs that Carl ate.
The three ate a total of 103
So
Andy ate 5 more than Barry
So
Carl ate 10 less than Barry.
So
How many did each eat?
Barry ate 36 hot dogs.
Andy at 36+5 = 41 hot dogs.
Carl ate 36-10 = 26 hot dogs.

Answer:
-4/5
Step-by-step explanation:
Let α and β be the roots of the quadratic equation
ax²+bx+c = 0
Sum of roots α + β = -b/a
Product of roots αβ = c/a
Given the equation 16x²+4x+5 = 0
a = 16, b = 4, c = 5
Sum of roots α + β = -4/16 = -1/4
Product of roots αβ = 5/16
To calculate 1/α + 1/β, we will need to find the LCM first'
1/α + 1/β
= (β+α)/αβ
= sum of roots/product of roots
= (-1/4)/(5/16)
= -1/4×16/5
= -4/5
The answer is C
the mean is the average which is solved by adding up all of the numbers and then dividing that by how many numbers there are, 45/5 = 9
