Step-by-step explanation:
Let the larger integer be x
Hence, the smaller integer = x-2
Hence,
Reciprocal of the x= 1/x
Reciprocal of x-2= 1/ x-2
Hence. their sum=
![\frac{1}{x} + \frac{1}{x - 2} \\ = \frac{x - 2 + x}{x(x - 2)} \\ = \frac{2x - 2}{ {x}^{2} - 2x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7Bx%7D%20%20%2B%20%20%5Cfrac%7B1%7D%7Bx%20%20-%202%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7Bx%20-%202%20%2B%20x%7D%7Bx%28x%20-%202%29%7D%20%5C%5C%20%20%3D%20%20%5Cfrac%7B2x%20-%202%7D%7B%20%7Bx%7D%5E%7B2%7D%20%20-%202x%7D%20)

Answer:
We need to sell the nuts at 35 dollars to make $20 profit
Step-by-step explanation:
Profit = Selling price - cost
We know we want a 20 dollar profit
The cost of the nuts is 15 dollar
Substitute this in
20 = Selling price -15
Add 15 to each side
20+15 = Selling price -15+15
35 = Selling price
We need to sell the nuts at 35 dollars to make $20 profit
Answer:
the expression is equal to -27
whichever expression equals -27 is the answer
Step-by-step explanation:
Answer:
c=7p
Step-by-step explanation:
Each pound costs $7. If we were to buy 1 pound, it would be $7, 2 pounds: $14, 3 pounds, $21. Therefore, 7 is being multiplied by the number of pounds to find the cost.
7 multiplied by pounds, p, is:
7p
And the expression above is equal to the total cost, c, so our equation is
c=7p
