Answer:
60
Step-by-step explanation:
After adding 88 red marbles, there are 50 blue marbles out of the 204 marbles total.
Let the number of blue marbles to be added be x.

Answer:
f = 2 + -15x-1 + x
Step-by-step explanation:
Simplifying
f(x) = x2 + 2x + -15
Multiply f (x)
fx = x2 + 2x + -15
Reorder the terms:
fx = -15 + 2x + x2
Solving
fx = -15 + 2x + x2
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'x'.
f = -15x-1 + 2 + x
Simplifying
f = -15x-1 + 2 + x
Reorder the terms:
f = 2 + -15x-1 + x

When we go from 3 avocados to 9 avocados, we're <em>mulitplying the number of avocados by 3. </em>If we triple the number of avocados, we'll also have to triple the tablespoons of cilantro, which would give us 2 x 3 = 6 tablespoons of cilantro for 9 avocados.
