1 answer:
Answer:
D(x) = 3x
Step-by-step explanation:
Micah travels at a rate of 'x' feet over a specific period.
Linda travels at a rate of '2x' feet over that same period.
Since they are walking in opposite directions, the total distance they have walked towards one another (D) can be determined by adding both distances:
The expression that describes the number of feet they have walked toward one another is D(x) = 3x.

Total number of marbles:
75 + 50 + 100 + 25 = 250
Probability of selecting a red marble:
25/250 (since 25 out of 250 marbles are red)
Since the top and bottom of this fraction are both divisible by 25, we can go ahead and divide them both by 25, simplifying to 1/10.
Probability of selecting a green marble:
50/250
Simplifies to 2/10
Simplifies to 1/5.
Probability of selecting a blue or orange marble
(75+100)/250
175/250
Simplifies to 7/10.
To find the probability that each event occurs in order, simply multiply them all together.
