2 and 3

Because integers are numbers that are whole and not negative.

Let the capacity of bus be x students

And van be y students, now ;

From the given statements we get two equations ~

multiply the equation (2) with 2 [ it won't change the values ]

Now, deduct equation (1) from equation (3)

Therefore each bus can carry (x) = 45 students

Now, plug the value of x in equation (1) to find y ~

Hence, each van can carry (y) = 17 students in total.

**Answer:**

independent is the time. time does change throughout the experiment.

Dependent is texting speed as it can vary.

hope this helps :)

B.) (1,1) (2,5) should be your answer.

**Answer:The sum of the interior angles of a triangle are equal to 180o. To find the third angle of a triangle when the other two angles are known subtract the number of degrees in the other two angles from 180o.**

**Example: How many degrees are in the third angle of a triange whose other two angles are 40o and 65o? Answer: 180o - 40o -65o = 75o**
