1 What is the value of x in the equation 8x - 5(x - 1) = 20?

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

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 %

part a: 1.08

part b: 27.59
