Answer:
62
Step-by-step explanation:
4*7 = 28
(14 - 1 - 4) * (7 - 4) = 27
1 * 7 = 7
7 + 28 + 27 = 62
It would be 7 out of 11 because there are 8 marbles and you only took out one white marble
The correct answer is p/rs.
In order to find this first state the direct variation with the constant k included.
p = krs
Now to find the value of k, we simply divide away the r and s
p/rs = k
We can model the equation:y = m x + b, where y is the total profit and x is the number of hotdogs sold.The system of equations is:
90 = 40 m + b210 = 80 m + b---------------------b = 90 - 40 m210 = 80 m + 90 - 40 m210 - 90 = 40 m120 = 40 mm = 120 : 40m = 3b = 90 - 40*3b = 90 - 120b = - 30Answer: The equation is y = 3 x - 30
