First, you get you equation, which is 54x-540=918. Then you solve your equation. First, add 540 to both sides, get 54x=1,458. Then divide both sides by 54, and get x=27
Answer:
Step-by-step explanation:
If k items out of 20 total items are defective, then the number of non-defective item is 20 – k. The probability of choosing 5 items where all of them are non-defective is
- For the 1st slot the chance is (20 – k)/20
- For the 2nd slot the chance is (20-k-1)/(20-1) = (19-k)/19
- For the 3rd slot: (18 – k)/18
- 4th : (17 – k)/17
- 5th: (16 – k)/16
The probability in total would be
So the probability of selecting at least 1 defective item is the inverse of this, which is
The true equation will be f(6) = 0. Then the correct option is C.
<h3>What is a function?</h3>
A statement, principle, or policy that creates the link between two variables is known as a function.
The function f(x) is given by the set of ordered pairs.
{(1,0), (–10,2), (0,6), (3,17), (–2,–1)}
Then the function can be written as
f(abscissa) = ordinate
Then the function will be
f(0) = 6
Then the correct option is C.

Answer:
2 1/4
Step-by-step explanation:
We need to see how much clay they used if each person in that group used 3/4 clay. There are 4 people in the group.
=> 3/4 x 4 = 12/4 = 3
Now, we need to see how much clay they used if each person in that group used 1/4 clay. There are 3 people in the group
=> 1/4 x 3 = 3/4
Now, we need to see how much more clay was used.
=>3 - 3/4
=> 3/1 - 3/4
=> Take the LCM of the denominators and make the denominators equal.
=> 12/4 - 3/4
=> 9/4
They used 9/4 more clay.
Since there are no options with 9/4, we need to make this improper fraction into a proper fraction.
=> 9/4 = 2 1/4
They used 2 1/4 more clay.
4x−5=7+4y
subtract 7 from both side
4x - 5 -7 = 4y
4x -12 = 4y
divide by 4
4x/4 -12/4 = 4y/4
x-3=y
