Answer:
The difference of fifty-four and seven times a number is written as 54 - 7x.
Step-by-step explanation:
Given: expression “the difference of fifty-four and seven times a number”
We have to write the given algebraic expression represents “the difference of fifty-four and seven times a number”
Consider the given algebraic expression represents “the difference of fifty-four and seven times a number”
Let the number be x
Then, seven times a number is 7x
And the difference of fifty-four and seven times a number is written as 54 - 7x.
Thus, The difference of fifty-four and seven times a number is written as 54 - 7x.

A) Add the distances together and divide by the number of attempts:
50.7 + 49.4 + 52.3 + 48.9 + 51.6 = 252.9
252.9 / 5 = 50.58
The average was 50.58 m.
B) Add 52.5 to the total above and divide by 6:
252.9 + 52.5 = 305.4
305.4 / 6 = 50.9 m.
Now subtract the average from above:
50.9 - 50.58 = 0.32 difference.
This question requires the manipulation of the Ideal Gas formula. By moving the variables around, you'll get :
V = nRT/P
n = PV/RT
