All you have to do is to determine the # of degrees covered in 1 hour. Divide "15 deg in 2 hrs" by 2; you'll get
(15/2) deg / 1 hr
Cheeseburgers = c
hot dogs = h
5c + 2h = 19.75
Hope this will help u...:)
Answer:
Step-by-step explanation:
Student : teacher = 5 : 2
Number of students = 5x
Number of teachers = 2x
<u>Last year:</u>
Last year Total = 56
5x+ 2x = 56
7x = 56
x = 56/7
x = 8
Number of students = 5*8 = 40
Number of teachers = 2*8 = 16
<u>This year:</u>Total = 70
5x + 2x = 70
7x = 70
x = 70/7
x = 10
Number of students = 5*10 = 50
Number of teachers = 2*10 = 20
I think the answer is x=any real number
