The sum of two numbers is 12. the first number, x, is twice the second number, y. which system of equations could be used
to find the two numbers?
(x + y = 12
1x=2+1
x + y = 12
1 x = 2y
o s xy = 12
x=2+1
os xy = 12

step-by-step explanation:

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 %
