Given:

To find:
Which statement are true?
Solution:
Option A: The entire expression is a sum.
It is true because it performed addition operation.
Option B: The coefficient of s is 3.

It is not true because the coefficient of s is
.
Option C: The term
is a quotient.
If we divide 7 by r, we obtain a quotient.
So it is true.
Option D: The term
has a variable.
It is not true because it does not contain any variable.
Therefore the entire expression is a sum and the term
is a quotient are true statement.
I do believe the answer is D
Answer:
x = 5/7
Step-by-step explanation:
4 (0.25 - 2) = x - 0.75 (16 - 8x)
1 - 8 = x - 12 + 6x
1 - 8 + 12 = x + 6x
5 = 7x
5/7 = x
