48+56=104; 170-104= 66. The librarian needs to pack 66 more books.
15,75 - 100 %
100 % = 100/100 = 1
Then every number multiplied by 1 is 100 % of itself.
If the book was marked up 65% of what is was before, it makes a price of 165% when compared to the original.
165% = 165/ 100 = 1,65
15,75 . 1,65 = 25,9875
25,99 is the nearest option.
a)25,99
Answer:
x=8
z = 115
Step-by-step explanation:
65 and 13x - 39 are vertical angles so they are equal
65 = 13x - 39
Add 39 to each side
65+39 = 13x - 39+39
104 = 13x
Divide each side by 13
104/13 = 13x/13
8 =x
65 and z are supplementary angles because they form a straight line. This means they add to 180
65+z = 180
Subtract 65 from each side
65+z-65 = 180-65
z = 115
X-intercept; -.25
y-intercept; -3
