Answer:

The probability is 12/32

Step-by-step explanation:

If there are 12 red marbles and 20 yellow marbles, then there will be a 12/32 chance that you pick a red marble

This is because out of 32 marbles, you have 12 red marbles that you could pick, which gives you a 12/32 chance that you will pick a red marble. This can also be said as a 37.5% chance.

Rewrite the quadratic equation 2x squared plus 12x plus 1 equal y
Sladkaya [172]

Answer:16x+1 = y

Step-by-step explanation:

2x squared is basically 2x times 2x which is 4x. So now that you eliminated that you have 4x+12x+1 = y . Now you have to group like terms. 4x+12x= 16x. So now you have 16+1 = y.

Not sure how to do this​
irinina [24]

Answer:2x × 3 (Don't solve it cause you cant)

Step-by-step explanation:For the first one in parentheses you can't do it because their has to be an x with the two so you can do the problem.

For the next one you can do it. So for every letter that doesn't have a number their is always an invisible 1 in front of it. So it's 1x to the second power + 1x-1 so 1×1 is 1. 1x+1x=2x and the 2 and the one that doesn't have a letter equals 3. So the answer is

2x × 3 Hopefully this is correct and helps you out!

Using elimination process what is the answer for <br><br> 14x+2y=18<br> -7x-4=9 <br><br> use steps
AlekseyPX
Step 1; multiple equation 2 by -2: 14x+8y=-18
step2: subtract this new equation from equation 1 to eliminate x:
2y-8y=18-(-18)
-6y=36
y=-6
step 3: substitute y=6 in equation 2: -7x-4*(-6)=9, -7x=-15, x=15/7
