Miss lees class collected 3 more ball because 21-18 is 3. if i collect 18 balls and my friend collects 21 balls and then we add 21+18 we get 39 and then we put 39 in 13 equal groups we have 3in each group that is why they collected 3.
21-18=3
add 21+18=39
put in equal groups
divide 39 with 3 get thirteen make equal group get 3 in each group
*21-18=3
*21+18=39
*39 divided with 3=13
* 3 in each group
*Answer 3
Multiply 2 on both sides to get rid of the 1/2 on the x side. Then, the final answer would be x = 12
If logs are subtracting, you can divide the brackets and if they are adding, you can multiply the brackets. Also, if the number comes before the log, it's can be Taken up as a power. so you end up with:
6log(25-x^2) - [log(5+X) + log(5-X)]
= log(25-x^2) - log(25-x^2)
= log (25-x^2/25-x^2)
= log(1)
log
= 6.25%
= 0.0625
= 625/10000
= 1/16
