Which of the following can be used to illustrate that not all prime numbers are odd?
a. 1
b. 2
c. 3
d. 4
e. 5

B. 2
the reason for this is because 2 is even, but it is also a prime number because 2 can't be divided evenly by a number.

1 is kind of in debate as to whether it is a prime number or not. But it's odd anyway
2 is an even number, and is a prime number because it can only be divided by 1 and itself
3 is a prime number, but it's also an odd number
4 is an even number, but it can be divided by 1, 2, and itself, meaning it isn't a prime number
5 is a prime number, but it's also an odd number
So the answer is b. 2

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
