Find b of y = mx + b first using a modified version of the equation.
b = y - mx
b = -1 -(1.2×-3)
b = 13/5 = 2.6
y = 1.2x + 2.6 ← result of substituting values of m and b into y = mx + b
-1.2x + y = 2.6 ← result of subtracting 1.2x from both sides
12x - 10y = -26 ← result of multiplying previous equation by -10
6x - 5y = -13 ← result of dividing previous equation by 2
ANSWER: 6x - 5y = -13

Mixed numbers are basically sometimes a sign of division. You need to turn the mixed number into an improper fraction.
Steps:
Multiply the whole number by the denominator of the fraction and then add that product to the numerator. Leave the denominator as it is before.
Example:
2 1/4
2x4=8
8+1= 9
Answer: 9/4
Then you can divide!
12.8 degrees
sin = o/h
sin(x) = 12/54
sin^-1 (12/54)
= 12.8 degrees
So the angle that's next to the 62 is 118. Now that means the other angles have to add up to 62. 62-14= 48 and 48/2 is 24 so X=24. Good luck! :)
