Answer: 3
Step-by-step explanation:
-3 + 4x = 9
if u add 3 to 9, u get 12. 12 divided by 4 is 3
Answer:
![\frac{1}{524160} or 1.910^{-6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B524160%7D%20or%20%201.910%5E%7B-6%7D)
Step-by-step explanation:
In order to solve this, you would need to multiply the probability of you choosing the one that goes first, so 1 in 16 discs, then the next one so 1 in 15, and so on untill the fifth disc.
So you would have to do this:
![(\frac{1}{16})(\frac{1}{15})(\frac{1}{14})(\frac{1}{13})(\frac{1}{12})\\\frac{1}{524160}](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B16%7D%29%28%5Cfrac%7B1%7D%7B15%7D%29%28%5Cfrac%7B1%7D%7B14%7D%29%28%5Cfrac%7B1%7D%7B13%7D%29%28%5Cfrac%7B1%7D%7B12%7D%29%5C%5C%5Cfrac%7B1%7D%7B524160%7D)
That is the probability that the rack ends up in alphabetical order, if you pull discs randomly, 1 in 524160 chances.
First option : 12 is not a factor of 30
Step-by-step explanation:
We are asked to find if the given choices are a factor of 30 or not.
There are two methods to check whether a number is factor of another or not.
1. First states that we should find the factors of the number and then check if the given number exists in the factors or not.
2. we can divide the number by factor, if the division is complete without any remainder, then the divisor is a factor.
So,
for 12, we will divide 30 by 12
=![\frac{30}{12} = 2.5](https://tex.z-dn.net/?f=%5Cfrac%7B30%7D%7B12%7D%20%3D%202.5)
The quotient should be a whole number in order for 12 to be factor of 30. as the quotient is not a whole number, 12 is not a factor of 30

Answer: $12.61
Step-by-step explanation:
Given : Total cost of meal for 5 people = $52.95
Jenna ordered a dessert for $2.50.
Total cost other 4 need to pay = $ (52.95- 2.50) = $ 50.45
Now , each person will pay ![=\$\dfrac{50.45}{4}\approx \$12.61](https://tex.z-dn.net/?f=%3D%5C%24%5Cdfrac%7B50.45%7D%7B4%7D%5Capprox%20%5C%2412.61)
Hence, each of the other person need to pay $12.61 .
the equation of the line is
y = 6/5xy + 7/5x - 2/5
