Answer:
-6
Step-by-step explanation:
This is similar to collecting like terms in Algebra, that is
- 2x - 7x + 3x = x(- 2 - 7 + 3) = - 6x
Similarly
-2 - 7 + 3
=(- 2 - 7 + 3) = - 6

Answer: 16
Step-by-step explanation:
From the question, we are informed that there are 25 markers in a bag: 5 red, 5 yellow, 5 blue, 5 green, 5 purple and that one marker is drawn out of the bag, then put back in.
The probability of picking a blue marker will be: = 5/25 = 1/5
Therefore, the number of times that a blue marker will be expected to be picked in 80 draws would be:
= 1/5 × 80
= 16 times
