Solve for x. 5(x – 10) = 30 – 15x

x = 4

Step-by-step explanation:

5(x – 10) = 30 – 15x

Distribute

5x -50 = 30-15x

Add 15x to each side

5x+15x – 50 = 30 – 15x+15x

20x-50 = 30

Add 50 to each side

20x-50+50 = 30+50

20x = 80

Divide by 20

20x/20 = 80/20

x =4

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 %
