Answer:
5/8
Step-by-step explanation:
1/4+3/8=5/8
The answer is:
A) If a = b, then a + c = b + c.
and C) If w + 2 = 7, then w + 2-2 = 7- 2.
The height of an airplane as it descends to an airport runway is a quantity which has a unit that is usually rounded to a certain terminating degree of accuracy (i.e. 1, 2, ..., n decimal places)
Thus the set of rational<span> numbers best describes the height of an airplane as it descends to an airport runway.
A rational number is a number which can be represented in the form a/b where a and b are integers. It is usually identified by a terminating or a recurring decimal number.

You want to "solve" this formula for s.
7s+4
If t = ----------- , then 2t = 7s + 4. Subtract 4 from both sides. Then
2
2t - 4
7s = 2t - 4, and s = -------------- (answer)
7
