Bart has 11 more baseball cards than Tom. Together, they have 163 baseball cards. How many baseball cards does Tom have? a. Tom has 152 baseball cards.

b. Tom has 65 baseball cards.

c. Tom has 76 baseball cards.

d. Tom has 87 baseball cards.

c

Step-by-step explanation:

If Bart has 11 more than Tom, you can't have a. If the addition is 163, then you can add 76 and 87. Bart has 87 and Tom has 76.

c

Step-by-step explanation:

Let Bart's cards = t

Let Tom's cards = b

Adding up Bart's and Tom's cards will add up to 163 like this

b + t = 163

Also Bart has 11 more than Tom

b = t + 11

Plug in the new b

t + 11 + t = 163

2t + 11 = 163

Subtract 11 from both sides

2t + 11 = 163

    - 11   - 11

2t = 152

Divide both sides by the coefficient, 2, to isolate the variable, t.

2t/2 = 152/2

t = 76

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9
