Answer:
y = -1/3x -2
Step-by-step explanation:
Restaurant 1 : y = 7k + 39
restaurant 2 : y = 2k + 44
7k + 39 = 2k + 44
7k - 2k = 44 - 39
5k = 5
k = 5/5
k = 1
y = 2k + 44
y = 2(1) + 44
y = 2 + 44
y = 46
Dinner would cost $ 46 at either restaurant if Lina's lobster weighed 1 kilogram.
The answer would be D. hope this helps :))
Answer:
30
Step-by-step explanation:
First, you need to find the original number whose 36% is 180.
To do so, you can use the generic equation below:

Now plug in the variables
resultant = 180 because the resulting number of the % is 180
percent = 36% because 180 is 36% of number
original number = represented by x

36 * x = 180 * 100
36x = 18000
x = 18000/36 = 500
Next, find 6% of the original number, 500
To do that, simply plug in the numbers into the generic equation used above:
resultant = represented by x
percent = 6%
original number = 500

100 * x = 6 * 500
100x = 3000
x = 3000/100 = 30
