I need help on a math assignment.

(18 , - 10)

Step-by-step explanation:

5x + 4y = 50 (1)

x + 2y = - 2 ... (2)

Solve (2) for "x"

x = - 2y - 2 (3)

(3) > (1)

5(- 2y - 2) + 4y = 50 ⇔ - 6y - 10 = 50 ⇒ y = - 10 (4)

(4) > (2)

x + 2(- 10) = - 2 ⇒ x = 18

(18, - 10)

don't report but were is the digram

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 %
