Dwight has 3 baseball cards, and ellis has 9 baseball cards. if dwight and ellis put their baseball cards together and then divide them up equally, how many will each one of them have?

6 baseball cards.

Step-by-step explanation:

We have been given that Dwight has 3 baseball cards, and Ellis has 9 baseball cards.

First of all, we will find total number of baseball cards by adding 3 to 9.

Since we need to divide baseball cards equally between Dwight and Ellis, so we will divide total number of cards by 2.

Therefore, Dwight and Ellis will have 6 baseball cards each.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
