Two bags, A and B, each contain only green marbles and red marbles.

There are 6 green marbles and 4 red marbles in bag A.

There are 8 green marbles and 2 red marbles in bag B.

One marble is going to be taken at random from bag A and placed in bag B.

A marble is then going to be taken at random from bag B.

Work out the probability that this marble will be a green marble.​

Step-by-step explanation:

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
