14/21 + 1/7 = 17/21
The following is the answer.
A minus and a minus makes a plus A plus and a plus makes a plus A minus and a plus or plus and a minus makes a minus 7 - -2 is a minus and a minus Therefore the answer is 7 + 2 = 9
It is: 4x -34x^2 -21 simplified
x=3 actually its 7
-21 + 14 = -7
There is nothing to "solve". 21 is greater than 14. Adding a positive amount (three eighths) to the left makes it even greater.
32+14+20+18+16+31+21+16=168
14/21 + 1/7 = 17/21
21
Answer: 14
2/3 + 1/7 + 4/6 = 14/21 + 3/21 + 14/21 = 31/21 = 1 10/21
It is: 10x+14 simplified
Yes.
1 + 2 + 3 + 4 + 6 + 7 + 12 + 14 + 21 + 28 + 42 = 140
The numbers are 14 and 7 because 14+7 = 21 and 14-7 = 7
14 and 11 21sts 140/21 + 165/21 = 305/21 or 14 and 11/21
