First, you put each fraction into its greatest common denominator:
5/20 - 12/20. This then gives you the answer - 7/20.
Let x be the page number then x+1 would be the other page number (because the pages are two facing pages which means they follow on consecutively)
Then
(x)(x+1) = 156
x^2 + x - 156 = 0
x = 12 or x = -13( but x can't be a negative number)
so x = 12
and the next page is 13
Step-by-step explanation:
l x 3 = c
k + 5 = l
(c + l + k) x 2 = 25
c = 33
l = 11
k = 6
Answer:
b = 5
Step-by-step explanation:
89b = 411 + 34 (445)
89b = 445
b = 5
It is a an exponential function. And it is not A.
The answer is B)
