Answer: The answer would be 8.
Step-by-step explanation: I'm going to assume you mean 7 8/13 is a mixed fraction. So you multiply the denominator, 13, multiply 7 to that, then add 8 to it and the denominator would be the same as before. That should give you 99/13. When you divide, you get around 7.6, rounding closest to 8.
If there are 10 wild cards there are 50 standard cards. 8 and 40 can both be divide by 4, which makes 2/10. This means that there are 2 wild cards for every 10 standard cards. If there are 50 wild cards, you simply multiply 2/10 by 5. This will give you 10/50. 10 wild cards in 50 standard cards.
Answer:
-1/4
Step-by-step explanation:
The slope is found by
m = (y2-y1)/(x2-x1)
= (-1-2)/(7- -5)
= (-1-2)/(7+5)
= -3/12
= -1/4
O = 2i - 1
o = output
2 i = twice the input
then -1 = one less
