To get the answer we have to find 55% of 9.
First step is rewrite 55% as 0.55
Second and the last step is to multiply 0.55 times 9
0.55*9=4.95~=5 -its the answer

Firstly, you should find 10% of 9, which is 0.9 You've then got to multiply this by 5.5, as you've got 55 books. 0.9x5.5= 4.95 Therefore, as you cannot have .95 of a books, this has to be rounded to 5. Therefore, the library has 5 books out on the topic. Hope this helps :)

If 2x +y=8, x+2y=4, find the value of x-y.<br> Please, help me
kifflom [539]

y = 8 -2x

x + 2 (8 - 2x) = 1

x + 16 - 4x = 1

x - 4x = -15

-3x = -15

x = 5

If x = 5, then we can substitute in...

5 + 2y = 1

2y = -4

y = -2

Now let us check that by substituting those values in to the equation

2x + y = 8

2 (5) + (-2) = 8

That is correct so we have the right values for x and y/
