How many whole numbers are between 1 and 50 that are divisible by 2?

25

Step-by-step explanation:

The first number in the range 1 - 50 that is divisible by 2 is 2 itself.  Then 4, 6, 8, ....

Here's one way to think and count:

In the table, the number on the right is half the number on the left.  The numbers on the right are just counting numbers (natural numbers), so there are 25 even numbers between 1 and 50.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
