--Percent means out of 100, so 20% = 20/100
The prob in other words is asking
-- $60 is 20% of what number?
'$60' -- ---> 60
'is' -- ---> =
20% -- ---> 20/100
'of' -- ---> * (multiply)
'what number' ---> x (variable)
Thanks for your equation!
This problem seems tricky, but is pretty simple.
All we have to do is add:
3 - 7i + 8 + 4i
And combine like terms:
-3i + 11
Hope this helps!
-5x + 46 +4z
Combine like terms
-5x + 2x = -3x
-3x + -2x = -5x
14 - (-32) = 46
4z is left alone since it doesn't have a like term.
You would do $32/ the price of the train tickets.
