Answer:

Here are the answers. Hope this helps you!

Step-by-step explanation:

11/12*9/22 = rational (as the solution is 33/88 which is in p/q form with q not equal to 0 and p and q as integers.)

√5 *8 = 8√5 = irrational

3 + √17 = irrational (sum of a rational and irrational number is always irrational)

√3*√12 = √36 = 6= rational number

π - 2π = -π = irrational (since π is irrational)

-3/8 + 3/5 = -15+24/40 = 9/40 = rational

√6/2 - 1/2 = 1/2*√6 - 1 * 1/2 = 1/2 (√6 - 1) = irrational (in this case difference is irrational and the product is clearly irrational as well).

Answer: x = 8/3 ; or, write as: 2 2/3; or, write as, 2.66666667 .
_________________________________________________________
Explanation:
_________________________________________________________

Given: 5 − 1/2 x = 5/8 x + 2 ;
______________________________________________________
Change the 1/2 x to "4/8 x" ;
_________________________________________________
Since "1/2" = "(1*4)/(2*4)" = "(4/8)"; and rewrite:
_________________________________________________
→ 5 − (4/8)x = (5/8)x + 2 ;
_________________________________________________
Subtract "5"; and add "(5/8)x" to EACH side of the equation:
________________________________________________
5 − (4/8)x − 5 + (5/8)x = (5/8)x + 2 − 5 + (5/8)x ;
_________________________________________________
to get:
_______________________________________
(1/8) x = (10/8)x − 3
___________________________________________________________
Multiply the entire equation (BOTH SIDES) by "8"; to get rid of the fraction:
_________________________________________________________

8 * { (1/8) x = (10/8)x − 3 };
______________________________
to get:
______________________________
x = 10x − 24 ;
___________________________________
Subtract "x" ; and add "24" ; to EACH side of the equation:
____________________________________________________
→ x − x + 24 = 10x − 24  − x + 24 ;
____________________________________________________
to get:
_____________________________________________________
→ 24 = 9x ; ↔ 9x = 24 ;
______________________________________
  → Divide EACH side of the equation by "9" ; to isolate "x" on one side of the equation; and to solve for "x" ;
_______________________________________
  → 9x / 9 = 24 / 9 ;
_______________________________________
  → x = 24/9 = (24÷3)/ (9÷3) = 8/3
_______________________________________________
→ x = 8/3 ; or, write as: 2 2/3; or, write as, 2.66666667.
