Answer:
k - 2 = 4d - 8
d + 1 = 4d - 8
Step-by-step explanation:
Daniel's age = d
Kevin's age = k
Given that, k = d + 3 -------------- (1)
Two years ago, the age of Daniel = d - 2
Two years ago, the age of Kevin = k - 2
Since, two years ago, Kevin was 4 times as old as
Daniel, k - 2 = 4(d - 2)
Opening the bracket,
k - 2 = 4d - 8
Since the value of k is d + 3 (see (1))
d + 3 - 2 = 4d - 8
d + 1 = 4d - 8
(I am just giving the answer cause I LOVE Linear Equation )
1 + 8 = 4d - d
9 = 3d
9/3 = d
3 = d
Therefore, Daniel's present age is 3 and Kevin's present age = 6

hope this helps! i got 100 on the quiz on edge
The probability of selecting or choosing seven marbles is 0.29.
Let E be the event of choosing seven red marbles.
According to the given.
Total number of balls in an urn = 13 + 11 = 24
Total number of red marbles = 13
Total number of blue marbles = 12
Now, the total number of ways of selecting 12 marbles from 24 = 
And the number of ways of selecting 7 red marbles = 
As, we know that, the probability of any event can be calculated as by taking the ratio of favroble outcomes to the total number of outcomes.
Therefore, the probability of selecting or choosing seven marbles is given by

⇒ P(E) = 
⇒ P(E) = 792792/2704156
⇒P(E) = 0.29
Hence, the probability of selecting or choosing seven marbles is 0.29.
