Sam bought six new baseball trading cards to add to his collection. The next day his dog ate half of his collection. There are now only thirty - eight cards left. How many cards did Sam start with?

76

Step-by-step explanation:

Sam bought six new baseball trading cards to add to his collection. The next day his dog ate half of his collection. There are now only thirty eight cards left. Therefore, he started out with 76 baseball trading cards.

Dog ate half of his collection (not including the 6 new baseball cards)

38 are left.

38x2=76

38x2=76

Therefore, he started out with 76 baseball cards.

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
