i think it would be y=3/5
Let n = number of hikers
y = number of slices of bread per sandwich= 2
x = number of sandwiches for each hiker = 3
T = total number of slices of bread used for "n" hikers
The expression below represents the total number of slices of bread used for "n" hikers:
T = 2 slices *3x sandwiches *n hikers
Answer:
(W+4)(W+7)
Step-by-step explanation:
In the attached file
For 1 kilometer, it is 100,000 Centimeters.
We can rewrite this by subtracting the right side to get
... 3^(-x) -x^3 -x = 0
A graphing calculator shows this to have a solution near x=0.5.
_____
There are no algebraic means for solving such a combination of exponential and polynomial functions.
