To find the answer:
2books x 3pictures = 6books
Toby read 6 books in month one.
I would compute sqrt(1 + 160pi^2) first to get approximately 39.75093337
Add this to 1 and we have 40.75093337
Then divide over 2pi to get a final approximate result of 6.48571248
So x = 6.48571248 is one approximate solution
In short, I computed
only focusing on the plus for now.
----------------------
If you were to compute
you should get roughly -6.167402596 as your other solution. Each solution can then be plugged into the original equation to check if you get 0 or not. You likely won't land exactly on 0 but you'll get close enough.
The answer is in the picture below I used the square rooting method hope this is the answer you need!
Answer:
12
Step-by-step explanation:
the original ratio was 3/5 , so apply that to 20 and 3/5 of 20 is 12
