50 total students

  • 20 girls

Explanation:

total students: 100%

----------------

  • 60% → 30
  • 1% → 30/60
  • 1% → 0.5
  • 100% → (0.5 * 100)
  • 100% → 50

number of girls:

  • total students - number of boys
  • 50 - 30
  • 20

If f(x) = 3x - 1 and g(x) = x + 2, find (f - g)(x).
Marat540 [252]

Answer:

(f - g)(x) = 2x - 3

Step-by-step explanation:

(f - g)(x) is defined as subtracting the whole g(x) function from the f(x) function.

Hence, we can define it as:

(3x - 1) - (x + 2)

= 3x - x - 1 - 2

= 2x - 3

Therefore, (f - g)(x) = 2x - 3.

Hope this helped!
