Answer:
The value of d of the given equation is 8.67
Step-by-step explanation:
Given equation as :
3 d + 16 = - 2 × ( 5 - 3 d )
Or, 3 d + 16 = - 10 + 6 d
Or, 16 + 10 = 6 d - 3 d
So , 26 = 3 d
∴ d = 
= 8.67
Hence The value of d of the given equation is 8.67 Answer
Answer: Ayden has 11 football cards,44 baseball cards and 51 Pokemon cards which totals 106 cards all together
Step-by-step explanation:
STEP 1 :
Let x represent number of football cards
He has four times as many baseball cards as football cards, let baseball cards be = 4x
Pokémon cards contain 7 more cards than his baseball collection,let Poke mon cards = 4x +7
Step 2 :
Putting in equation we have that
Football cards + Baseball cards + Pokemon cards = 106 cards
Therefore,
x + 4x + 4x+7 = 106
9x + 7 = 106
9x = 106-7
9x = 99
x =99/9 = 11
therefore football cards , x = 11 football cards
baseball cards = 4x = 4 x 11 = 44 baseball cards
Pokemon cards = 4x+7= 4x11 +7 = 44 +7 =51 Pokemon cards
