-50x :)
characters bc it has to be 20
Multiply -2 by 3z and -4y
-6z + 8y -z
subtract z from -6z
-7z + 8y should be your answer
Drop the egg from half way up the building. This divides the search space in half. If it breaks, start on the bottom floor and work your way up the top :) Hope it works
<span>1A + 2C = $24, or, since A = 2S, you can write this as
2S + 2C = $24
The difference between $17 and $24 is $7, so this must be the cost of a child's ticket. Subtract this from $17 and you get $10, which must be the cost of 2 Senior tickets. So the Senior ticket costs $5, and the Adult ticket must cost $10.
Therefore 1 Adult and 1 Senior ticket costs $15 </span><span>
