Let a and b be integers and b>a, then we can say:
(b-a)/3=5 now multiply both sides by 3
b-a=15
b=15+a
So there are infinitely many pairs of integers that satisfy the conditions given in the problem. For any value a, b will be 15 units greater.
45+1.99x=68.88
Subtract 45 from both sides
1.99x = 23.88
Divide both sides by 1.99
X=12
We have been given that at north shire high school 87.5% of the teachers have a masters degree. Total number of teachers is 128.

Answer:
12a - 6b
Step-by-step explanation:

= 12a + (- 6b)
= 12a - 6b
