Help me due today it is math

B, C, and D.

Step-by-step explanation:

a)

d + 2 = 7

d = 5

b)

10 - d = 6

-d = -4

d = 4

c)

20 / d = 5

20 = 5d

4 = d

d)

4d = 16

d = 4

Hopefully this helps!

Brainliest please?

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
