Answer:
Step any explanation:
t & 1/r
t = k/r
When t =6 and r = 5
k = tr
k = 6×5
k = 30
Constant of proportionality is equal 30
Complete question :
A 48 inch board in to be cut into three pieces so that the second piece is twice as long as the first, and the third piece in 3 times as long as the first. If x represents the length of the first, find the lengths of all three
Answer:
Length of first piece = x = 8
Length of second = 2x = 8*2 = 16
Length of third = 3x = 8 * 3 = 24
Step-by-step explanation:
Let :
Length of first piece = x
Length of second = 2x
Length of third = 3x
The total lengtb of board = 48 inches
Hence,
First + second + third = 48
x + 2x + 3x = 48
6x = 48
x = 48 / 6
x = 8
Length of first piece = x = 8
Length of second = 2x = 8*2 = 16
Length of third = 3x = 8 * 3 = 24
It is called 'down payment'.

By the difference of "5 and a number", I assume you mean that number minus 5. In that case, the expression is 8 times (x-5).
If by "the difference of 5 and a number" you mean 5 minus that number, then the expression is 8 times (5-x).
The inverse of the function 
is 
Given the function 
We are to find its inverse
Step 1: Ley y = f(x)
Step 2: Replace y with x
Step 3: Make y the subject of the formula
Step 4: Take the square root of both sides
This shows that the inverse of the function is
