Answer:
21
Step-by-step explanation:
Hi there!
We are given the expression x(y-z), and we want to evaluate it if x=3, y=9, and z=2
As we're given the values of the variables, we can substitute those values into the expression to find out what the value of the expression is.
So substitute 3 as x, 9 as y, and 2 as z in the expression above
x(y-z)
3(9-2)
Now we must follow the order of operations; start by subtracting 2 from 9 (do the stuff inside the parentheses first)
3(7)
Now multiply 3 and 7 together

Hope this helps!
Answer:
D) 5985
Step-by-step explanation:
Total area: 150×100 = 15000
Area for stars: 6×6 = 36
Total area - area for stars = area for fans
15000-36= 14964
14964ft² for fans, each takes up 2.5 ft²
14964 ÷2.5 = 5985.6 fans
Since we can't have 0.6 of a person, we round down to 5985 fans
