Is there a picture of the shape, and is 4x - 2 AC or AB?
If that little dot after the '1' is a comma, then you're correct. Melting doesn't change the mass.
Answer:
Any number with 9 in the ten-thousands place. 90,000 is one such number.
Step-by-step explanation:
The 9 in 39,154 is in the thousands place. Its value is 9,000. In order for the 9 in a number to have a value 10 times that, or 90,000, the 9 must be in the ten-thousands place.
There are an infinite number of such numbers. We suspect you have a list you are to choose from. Pick the number with 9 where it is in the number 90,000.
X = 70 and y = 35, I hope this helps
