where is your calculator?
Percent error = |actual error - expected error/ expected error| * 100%
(|75-95|)/95 = 0.21
0.21 * 100% = 21% error
The answer would be D because all sides are equivalent.
Answer: Eric still needs
of a deck.
Step-by-step explanation:
You know that:
- Eric need 1/2 deck of playing cards.
- Eric has 2/7 of a deck.
Therefore, to find the fraction of a deck that Eric still needs, you must subtract 1/2 and 2/7:
- Find the least common multiple of the denominators:
![2=2*1\\7=7*1](https://tex.z-dn.net/?f=2%3D2%2A1%5C%5C7%3D7%2A1)
![LCM=2*7*1=14](https://tex.z-dn.net/?f=LCM%3D2%2A7%2A1%3D14)
- Now, you can make the subtraction:
![\frac{(7*1)-(2*2)}{14}=\frac{7-4}{14}=\frac{3}{14}](https://tex.z-dn.net/?f=%5Cfrac%7B%287%2A1%29-%282%2A2%29%7D%7B14%7D%3D%5Cfrac%7B7-4%7D%7B14%7D%3D%5Cfrac%7B3%7D%7B14%7D)
Therefore, he still needs
of a deck.
= 11/12 - 1/6q + 5/6q - 1/3
to add like terms, we must first convert 1/3 to a common denominator with 11/12
= 11/12 - 1/6q + 5/6q - 4/12
combine like terms
= (-1/6q + 5/6q) + (11/12 - 4/12)
add/subtract inside each parentheses
= 4/6q + 7/12
simplify 4/6 by 2
= 2/3q + 7/12
ANSWER: 2/3q + 7/12
Hope this helps! :)
