three-fourths of the sum of q and 5
The sum of p and q means (p+q). The difference of p and q means (p-q).
It is: 4*(q+p)
As an algebraic expression it is simply: 8+q
Yes, irrational. Let p = root 2 and q = root 3. Then (q - p)2 = 5 - 2root6, which is irrational because it is the sum of an integer (5) and an irrational (2root6), and so q - p (which is root3 - root2) is irrational.
21-q
the sum of q plus 5!
The sum of p and q means (p+q). The difference of p and q means (p-q).
q+8
1+q
q - p
The expression is simply: 9+q
It is: 4*(q+p)
As an algebraic expression it is simply: 8+q
Get your book open and work out the problem. You need to do this.
Yes, irrational. Let p = root 2 and q = root 3. Then (q - p)2 = 5 - 2root6, which is irrational because it is the sum of an integer (5) and an irrational (2root6), and so q - p (which is root3 - root2) is irrational.

I think so.Sum = m + q
