There are 12 coins in the bag. For the first case, the probability that a penny is selected from the bag is 5/12 because there are 5 pennies in the bag. Also, the next one is 3/11. Multiplying the probabilities,
(5/12)(3/11) = 8/121
Distribute on the left
3x-15=7x
Subtract 3x from both sides
-15= 4x
Divide both sides by 4
-15/4= x
Final answer: x=-15/4 or -3.75
Answer:

Step-by-step explanation:
To find the function h(x), that represents the total number of seats, we just need to multiply the functions f(x) (number of rows) and g(x) (number of seats per row):




So the function that represents the total number of seats is:
