Okay, so it might be a little difficult to explain it but here we go:
You find the LCD (lowest common denominator) and multiply the top and bottom half of the fraction by the LCD:
(1/x) times xy (since it is divisible by both x and y)
then you do the same for the bottom (2/y) times xy
The x's on the top cancel out leaving you with 1/y
The y's on the bottom cancel out leaving you with 2/x
So now you multiple the top half (numerator) by the reciprocal of the denominator. In other words, multiply (1/y) by (x/2).
The answer is x/2y
A start up cost for a company is $7.
It costs the company $2.91 to make each rubber duck.
The amount of ducks is q.
We have to determine the cost function for this company ( and $3.74 is connected with the revenue, not with the costs ).
Answer:
C ( x ) = 7 + 2.91 q.
Answer:
The answer is C

Answer:
Mario could solve using the following equation: x=(84-34.5)/8.25 which equals 6.
Step-by-step explanation:
If the tent comes with 7 feet of rope, we need to first convert that measurement to inches. Since there are 12 inches in one foot, then 7feet of rope= 7 x 12 = 84 inches. Of the 84 inches of rope, 34.5 inches of that will be used to tie a tarp on the top of the tent. With the remaining rope, Mario will need to cut sections that measure 8 1/4 or 8.25 inches. If 'x' represents the number of sections he can cut, he can set up the equation such that: x = (84-34.5)/8.25, or 6.
