Duane has 12 times as many baseball cards as tony. between them, they have 208 cards. how many baseball cards does each boy have?

Duane has 192 cards and Tony has 16

Step-by-step explanation:

If we write an equation and make Tony's amount of cards x, then the equation would be :12x+x=208

Therefore, 13x=208

and x will be 16

That means Tony has 16 cards.

Then since Duane has 12 times of tony's cards and tony has 16, 16*12 is Duane's amount of cards

Therefore Duane has 192 cards

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60
