Alexa is comparing the cost of lobster at two different restaurants. One restaurant called 'Lobster Foods' charges $18 for the l

obster meal, plus $7 per kilogram of her choice of lobster. On the other hand, at 'Megan's Lobster' she would have to pay $8 per kilogram for the lobster, plus $17 for the meal. Alexa theorized that the cost of the dinner at both restaurants could cost the same amount if the lobster had a certain weight. What is the weight of the lobster? How much would Alexa pay for her dinner?

Answer:

The weight of the lobster is 1 kilogram.

Alexa will pay $25 for her dinner.

Step-by-step explanation:

Let's call the amount of kilograms of lobster K and then formulate equations based on the problem information:

The price in Lobster Foods is L = 18 + 7*K

The price in Megan's Lobster is M = 17 + 8*K

To know how much kilograms of lobster will make both prices be the same, we just need to equate both equations:

L = M

18 + 7*K = 17 + 8*K

8*K - 7*K = 18 - 17

K = 1

The weight of the lobster is 1 kilogram, and Alexa will pay 18 + 7*1 = $25 for the dinner.

What is the answer for 4i over 3+7i
icang [17]

Answer:

see explanation

Step-by-step explanation:

given \frac{4i}{3+7i}

To rationalise multiply the numerator/denominator by the conjugate of the denominator

the conjugate of 3 + 7i is 3 - 7i, hence

\frac{4i(3-7i)}{(3+7i)(3-7i)}

distribute the numerator/denominator

= \frac{12i-28i^2}{9-49i^2}

[ note that i² = - 1 ]

= \frac{12i+28}{9+49}

= \frac{28+12i}{58}

= \frac{28}{58} + \frac{12}{58} i

= \frac{14}{29} + \frac{6}{29} i ← in standard form
