Answer:
8z
Step-by-step explanation:
3z+5+5z-5
Combine like terms
3z+5z +5-5
8z +0
all we have to do here is to combine like terms
so we can add 3z and 5z which would be 8z
then add 5 and -5 which would be 0
so the expression simplified would be 8z
work is attached and shown
$43.70
90.50 - 4 = 87.50
87.50 ÷ 2 = $43.70
