Answer: 30
Step-by-step explanation:
5 in fraction form is 5/1. You can't divide fractions so you keep the 5/1 the same, turn the divide sign into a multiplication sign, then flip the 1/6 to 6/1 then multiply across. The answer would be 30/1 or 30.

Answer:
x = 14
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, hence
4x + 14 + 2x + 15 + 5x - 3 = 180
11x + 26 = 180 ( subtract 26 from both sides )
11x = 154 ( divide both sides by 11 )
x = 14
