Simplest way to do this:
number of books= 120
percentage represented by 120= 100%
increase current percent by 55%= 155%
: . 55% increase = original number of books * (155%)
= 120 * (155/100)
= 186
The answer is positive since the slope is positive.
Order from least to greatest
-9/2, - 3, 1/2, sqrt(6), 4.2
answer
D.-9/2, - 3, 1/2, sqrt(6), 4.2
----------------------------------
sqrt(10) is irrational number and real numbers
answer is B.irrational number and real numbers
-------------------------
square root (81) = 9
square root (100) = 10
square root (93) is between 9 and 10
so answer
9< sqrt(93) < 10
The addition property of equality justifies this. You could also say that she simply subtracted 7, and then it would be the subtraction property of equality. This is the case because if you add or subtract (or multiply or divide) the same number on both sides of an equation, the equation will still be the same.
