2x + 3 = x -4 thats my question

-7

Step-by-step explanation:

Subtract xx from both sides.

2x+3-x=-42x+3−x=−4

2 Simplify  2x+3-x2x+3−x  to  x+3x+3.

x+3=-4x+3=−4

3 Subtract 33 from both sides.

x=-4-3x=−4−3

4 Simplify  -4-3−4−3  to  -7−7.

x=-7x=−7

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

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 %
