5 because 5/6 is equal to 15/18

Answer: B. (40,40)</h3>
Explanation:
<u>Given Inequalities</u>:
(i) 3x + 8y ≤ 480
(ii) y - x ≤ 20
For first inequality:
(a) y intercept: (0, 60)
(b) x intercept: (160, 0)
- Plot this line with a solid line and shade below.
For second inequality:
(a) y intercept: (0, 20)
(b) x intercept: (-20, 0)
- Plot this line with a solid line and shade below.
The point (40, 40) falls between these two inequalities.
D, one number is positive and the other is negative. The only way it could equal 0 is to cross the other out. An example is, -5+5=0
The answer is 16, all you must do is substitute x with the given value then solve, so 23-7
