Answer:
The third option, x = 2 over 3.
Step-by-step explanation:
x + 4/3 = 2
x = 2 - 1 1/3
x = 2/3
<em><u>Mark as brainliest!</u></em>
-2/3 is not whole, not natural, and not irrational.
From that list, the only thing it is is rational.

Step-by-step explanation:
Answer:
x= 13.5
Step-by-step explanation:
f(x) = 2x + 9
f(x) = 36
Set the 2 equations equal to each other;
2x + 9 = 36
Subtract 9 from both sides;
2x = 27
Divide both sides by 2;
x = 13.5
<em>Check:</em>
f(x) = 2x + 9
f(13.5) = 2(13.5) + 9= 27 + 9 = 36
