Hope this helps!
20 mysteries. Add 20% and 30% to get 50%. Then rewrite 50% as 50/100. Next multiply 50/100 by 40 to get 2,000/100.The last thing to do is simplify to get 20 and subtract 20 from 40 to get 20 mysteries.
Answer:17%
Step-by-step explanation: yeah
The commutative property of addition can be used to rarrange this to
... 0 + 18 + 34 + 26
Then the identity property of addition can be used to remove the 0 term
... 18 + 34 + 26
We can use the associative property of addition to form the sum of 34 and 26, convenient because 4 and 6 "make a 10". That sum is 60, so now the sum is
... 18 + 60
which is easily seen to be
... 78
