I think the answer to this is .6 or 1.7
Answer:
4/5 is greater
Step-by-step explanation:
60% = 60/100
4/5 = 80/100
80>60
From 86 books to 150 books. An increase of 64 books.
(150 - 86) / 86 = 64 / 86 = 0.744 * 100% = 74.40% or 74% increase
150 / 86 = 1.744 * 100% = 174.40%
86 is the basis. It is 100%
If the problem asks for the value of the percentage increase and the rate is given 74.4% of 86. Then 86 * 74.4% = 64. You just add 64 to 86 to get the new total of books which is 150.
Answer:
step 1: move the -4 to the right: x^2 -2x = 4
step 2: add 1 to each side: x^2 -2x + 1 = 4 + 1
step 3: factor the left side and simplify the right side: (x-1)^2 = 5
step 4: take the square root of each side: x - 1 = sqr root of 5
step 5: move the 1 to the other side:
and
