The last one, v = -2,000y + 20,000
A prime number is a number that has only two factors: 1 and itself
For example, the number 7 has two factors: 1,7 This makes 7 a prime number
Since the number has to be greater than 50, we can go to the next whole number; 51
51 has four factors, 1,3,17,51 This is not our prime number
52 is even so obviously it's not prime because you can divide by two
53 has only two factors; 1,53 This means that its prime and the answer is 53 :)

It has to be C- addition and subtraction signs.
The answer is B. 5 degrees celcius
The formula is
(temprature in celcius)=(temprature in fahrenheit -32) *5/9
or
Temprature in celcius=( temprature in fahrenheit-32) * 1.8
