We need to start from the innermost parenthesis and work our way out.
The first parenthesis is . These are not like terms because one involves a variable, while the other is a constant term. Two terms are summable if they involve the same power(s) of the same variable(s).
So, we can take one step outwards, and we arrive to the square brackets. We have
and 2z and -13z are like terms, so we can sum them:
Finally we arrive to the whole expression, which is
Because, again, 5z and 11z were like terms.

Answer:
19-6j/5
Step-by-step explanation:
Hello!
First you find out the amount of balloons by adding them up
10 + 12 + 15 + 8 = 45
Then you add all the balloons that are not green
10 + 12 + 15 = 37
Then you put the amount of balloons that are not green over the total amount of balloons
The answer is 37/45
Hope this helps!
