I only need to know the first one

x = 9

Step-by-step explanation:

2/3x +5 = -2/6x +14

Simplify

2/3x +5 = -1/3x +14

Add 1/3x to each side

2/3x + 1/3x +5 = -1/3x +1/3x +14

3/3x +5 = 14

x+5 = 14

Subtract 5 from each side

x+5-5=14-5

x = 9

answer: what in the world is this

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 %
