Answer:
255+35-75
Step-by-step explanation:
Since we are trying to find the account balance, we consider anything in or going to the account to be positive.
255 is positive since it is in the account
35 is positive since it is going into the account
75 is negative because it is going out of the account
so the final expression to express the amount is the checking account would be 255+35-75
Answer:
We have been given the equation: x+y+z. Now these are variables. Thus, we have to fill in the values given: where x = 18, y = 6 and z = 1. Let's fill these values in.
<em>x+y+z</em>
<em>= 18+6+1</em>
<em>= 18+(7)</em>
<em>= 25</em>
