12 * 2 1/2 = 30
Katoni (or Kenton) bought 30 pencils.
Let the projected number of work hours be w.
Then the number of hours he actually worked was 1.25w. This represents the number of hours that Bob actually spent on the project.
Another way in which to answer this would be as follows:
Actual work hours = w + h (h hours beyond the projected w work hours).
This w + h is equivalent to 1.25w. This means that h = 0.25w.
Answer
(x-1) (x-4)
Step-by-step explanation:
I did this not long ago in class so that's the answer
The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable
A. f(x) because it's subtracting and subtraction meaning getting smaller ad it uses in the question so your answer is choice A.
