Answer:
The answer is x + 2 5/6.
Step-by-step explanation:
Emilie rides her bike x miles before it gets a flat tire.
She walks 1/3 mile to a bus stop and then goes another 2 1/2 miles or 5/2 miles on a bus.
The equation would be:
x + 1/3 + 2 1/2
But, since that isn't an option, we have to simplify the equation.
x + 1/3 + 5/2
= x +
= x + 17/6
= x + 2 5/6
Thus, the answer is x + 2 5/6.

Answer:
Manufacturers has to produce 63 DVD/Blu-Ray players to achieve a minimum cost of $644
Step-by-step explanation:
The cost equation is given as:
This is a quadratic equation in general form, which is:
Matching, we can say:
a = 0.04
b = -5
c = 800
The minimum occurs at
and the minimum value would be to place that "x" value into the equation.
First, we find the minimum using values of a and b:
Plugging this into original, we get:
Rounding off to nearest whole number, we can say:
