Answer:
(B) the first box
..................................
The line is 180 degrees in total so your equation would be-
X-6 + 8x + 24 = 180
9x + 18 = 180
9x = 162
Answer is: x = 18
5/22 the number you get from the total becomes the numerator and the total amount becomes the denominator
First set up an equation in n:-
3n + 10 = 8n
add -3n to both sides;-
10 = 5n
The cube root of -27 is -3
3√-27 = -3
You can check this by plugging your answer back it
X= -3
-3^3 = -27
