Answer:
x+10 x ≠ 60
Step-by-step explanation:
(x^2−50x−600)
----------------------
(x−60)
Factor the numerator
(x-60)(x+10)
-------------------
(x-60)
Cancel the like terms
x+10
Answer:
42%
Step-by-step explanation:
The first step is to calculate the difference in the number of fishes from the beginning of the day to the end of the day.
90 -52
= 38 fishes
Therefore the percent decrease can be calculated as follows
= 38/90 × 100
= 0.422 × 100
= 42.2 %
= 42% ( to the nearest cent)
