Answer: d
Step-by-step explanation:
The probability of not being purple is the probability of the three other colors. Suppose the number of purple marbles is x. Then we have 20+30+40+x = 90 + x marbles. Then the probability of not being purple is 90/(90+x). If this fraction can have a lowest term for some value of x, then the numerator of this lowest term must be a factor of 90.
Checking through the options, only option D has a non-factor of 90 as its numerator.
The answer to this is 49995.
Answer:
The correct answer is option A. 18x + 15
Step-by-step explanation:
It is given an expression in variable x,
5(4x + 3) - 2x
<u>To simplify the given expression
</u>
5(4x + 3) - 2x = (5 * 4x) + (5 * 3) - 2x (open the bracket)
= 20x + 15 - 2x
= 20x - 2x + 15
= 18x + 15
Therefore the correct answer is 18x + 15
The correct option is option A. 18x + 15
