D. Is the answer because its the only one that makes sense.
Answer:
Your answer would be C
Step-by-step explanation:
18 inches was the height of the baby when they were born since it isn't y which would be the current height of the baby now in months that tells me months have passed which includes x is the age of the baby in months.
-2y - 2y - 8 = -4
Move the -8 to the -4, and that makes
-2y -2y = 4
Add the -2ys together and that makes
-4y = 4
Then divide by -4, and you will get your answer of
y= -1
You have to plug the known x value into the problem. You know that x is the same thing as saying 5, so you can say that 6x is the same thing as 6(5) which equals 30, now that the x value is know there will not be any x’s in the solution. So the solution is just 30.
