ans: -6, equation: -3x+-9y=3
THIS IS SIMPLE GEOMETRY. You should be able to know that a line is equal to 180 degrees. 180-118=62 degrees. This is 4th grade math. TOO EASY. Just try doing it yourself.
A = 20 and B = 3 and C = 5 and D = 12 A = 20 and B = 3 and C = 12 and D = 5
TOTAL: 9 balls
Probability that first pick is black= 6/9=2/3
Probability that second pick is black (the first one is taken already, so subtract 1 from numerator and denominator.) = 5/8
Multiply both:5/8 x 2/3=5/12
Hint from another website:
\(5^3^k+1 + 1 = (5^3^k)^3 + 1 = (5^3^k+1)(5^2⋅3k − 5^3k+1)\)

Relationships between shirts:
Total - Pink - W =114- RED.
To find pink, we need this: Total - 24% - 114= W+198.
76% - 114= W+198
Now you should be able to carry on.
