Benny bought 9 new basketball trading cards to add to his collection. The next day his dog ate half of his collection. There are 43 cards left. How many cards did he begin with?
1 answer:
Answer: Benny started with 77 cards.
Step-by-step explanation:
The first step is to find what 43 is a half of. If we multiple 43 by two, we see that the answer is 86. As this number included the 9 cards he bought the day before, we must subtract 9 from 86, giving us 77.

Answer:

Step-by-step explanation:
2/3 +y =1/4
Subtract 2/3 from each side
2/3-2/3 +y =1/4-2/3
y = 1/4 -2/3
Get a common denominator
y = 1/4 (3/3) - 2/3 *4/4
= 3/12 - 8/12
=-5/12
or if
2/(y+3) = 1/4
Using cross products
y+3 = 2*4
y+3 = 8
y =8-3
y = 5
Answer:
x^2+y^2 = 9+16 = 25
x^2-y^2 = 9-16 = -7
