Answer 1

Favorite Answer

D) 3 classes

5*15=25X

75=25X

3=X

Answer 2

Total number of students in cafeteria = 25/5 * 15

= 5 * 15

= 75

Now,

Each class contains 25 students

Therefore, number of classes = 75/25 = 3

Answer 3

D) 3 classes

Answer 4

5 students per 15 tables

So, 5 X 15 = 75

Only, 25 students in each class:

75/25 = 3 classes - D

Answer 5

(Tables x Students Per Table)/Students Per Class = Classes

(15 x 5)/25 = 3 classes(D)

Answer 6

i think D not to sure only in 7Th grade (5 x 15 = 75 div. by 25 = 3 classes yep 3 classes so the answer is D 3 classes)

Answer 7

15*5 = 75

75/25 = 3 .

3 classes

Answer 8

2 numbers, L for sizable and S for small, upload as much as the variety of pizzas offered. L + S = 38. L circumstances the fee of a huge pizza is the money made advertising large pizzas. S circumstances the fee of a small is the money made advertising small pizzas. those 2 products are the finished quantity of money made advertising pizzas. (12.50)(L) + (9.00)(S) = 415.50. resolve the two equations for L and S to locate the numbers of vast and small pizzas offered.
