Answer:
C. 7
Step-by-step explanation:
We have been given a line plot which represents the estimated weights of alligators at Thompson Zoo. We are asked to find the number of alligators who weigh less than 450 pounds.
To find the total number of alligators who weigh less than 450 pounds we will add the number of alligators whose weight equals 400 pounds and 425 pounds.
We can see from our line plot 3 alligators weigh 400 pounds and 4 alligators weigh 425 pounds.

Therefore, 7 alligators weigh less than 450 pounds at Thompson Zoo and option C is the correct choice.

If n is odd then its cube is also odd because odd times odd is odd. When we add 5, an odd number, we get an even number.
If n is even, its cube is also even so adding an odd number makes the sum odd. So if the expression is odd, n must be even.
1. x-2(2x-3.5)=-14
x-4x+7=-14
-3x=-21
x=7
2. y=2(7)-3.5
y=14-3.5
y=10.5
hope this helps!
