Answer:
x = 23/5 OR 4.6
y = 157/15 OR 10.46
Step-by-step explanation:
x = 4x + 6x - 33 = 13
> 10x - 33 = 13
> 10x = 13 + 33
> 10x = 46
y = 4 (25/5) + 3y = -13
> 92/5 + 37 = -13
> 3y = -13 - 92/5
> 3y = - 157/5
Answer: A) (2+2) x 3
Step-by-step explanation: The answer to the problem (2 X 3) + (2 X 3) is 12 so we have to find the eqaution in the answers that equals 12,
B) 2 + (3+3) is equal to 8 so that can't be the correct answer
C) 2 x 3 x 3 is equal to 18 so that can't be the correct answer
D) (2 + 3) x (3+2) simplifies to 5 x 5 which is 25 so that can't be the correct answer
So that leaves us with A) (2+2) x 3 as the correct answer because it equals <u>12</u>
(n) is the set of <u>odd</u> natural numbers greater than 0.
Answer:
jice
Step-by-step explanation:
Step-by-step explanation:
Each roll has 6 possible outcomes, so two rolls have 36 possible sums. We can make a table showing what these sums are:
![\left[\begin{array}{ccccccc}&\textbf{1}&\textbf{2}&\textbf{3}&\textbf{4}&\textbf{5}&\textbf{6}\\\textbf{1}&2&3&4&5&6&7\\\textbf{2}&3&4&5&6&7&8\\\textbf{3}&4&5&6&7&8&9\\\textbf{4}&5&6&7&8&9&10\\\textbf{5}&6&7&8&9&10&11\\\textbf{6}&7&8&9&10&11&12\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccccccc%7D%26%5Ctextbf%7B1%7D%26%5Ctextbf%7B2%7D%26%5Ctextbf%7B3%7D%26%5Ctextbf%7B4%7D%26%5Ctextbf%7B5%7D%26%5Ctextbf%7B6%7D%5C%5C%5Ctextbf%7B1%7D%262%263%264%265%266%267%5C%5C%5Ctextbf%7B2%7D%263%264%265%266%267%268%5C%5C%5Ctextbf%7B3%7D%264%265%266%267%268%269%5C%5C%5Ctextbf%7B4%7D%265%266%267%268%269%2610%5C%5C%5Ctextbf%7B5%7D%266%267%268%269%2610%2611%5C%5C%5Ctextbf%7B6%7D%267%268%269%2610%2611%2612%5Cend%7Barray%7D%5Cright%5D)
Of the 36 sums, 10 are greater than 8, and 18 are odd.
P(A) = 10/36 = 5/18
P(B) = 18/36 = 1/2
