A bag contains 42 red marbles, 8 white marbles, and 6 gray marbles. You randomly pick out a marble, record its color, and put it back in the bag. You repeat this process 280 times. How many white or gray marbles do you expect to get? If you randomly pick out a marble and replace it 280 times, you can expect white or gray marbles to be chosen.

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x
