Answer:
Step-by-step explanation:
xy=xu-yu
50-30=20
xy = 20 xu=50 yu=30 xz =?
xy/yu = xz/zu
20/30 =
i think the question needs more information u have to send the photo
it should be like this
For three fair six-sided dice, the possible sum of the faces rolled can be any digit from 3 to 18.
For instance the minimum sum occurs when all three dices shows 1 (i.e. 1 + 1 + 1 = 3) and the maximum sum occurs when all three dces shows 6 (i.e. 6 + 6 + 6 = 18).
Thus, there are 16 possible sums when three six-sided dice are rolled.
Therefore, from the pigeonhole principle, <span>the minimum number of times you must throw three fair six-sided dice to ensure that the same sum is rolled twice is 16 + 1 = 17 times.
The pigeonhole principle states that </span><span>if n items are put into m containers, with n > m > 0, then at least one container must contain more than one item.
That is for our case, given that there are 16 possible sums when three six-sided dice is rolled, for there to be two same sums, the number of sums will be greater than 16 and the minimum number greater than 16 is 17.

Answer:
40+5x
Step-by-step explanation:
Eduardo put $40 in so the 40 is what he has already put in. Next you have $5 added in but it doesn’t say for how many months just that it’s each month so we put the x to represent out unknown so we can solve the equation.
