1/x(x-2) + 1/x = 5/x(x-2)

1/x(x-2) + 1/x = 5/x(x-2)

Let's clear the fractions by multiplying both sides by x(x-2)

1 + (x-2) = 5

x = 6

Check

1/(6(6-2))+1/6 = 5/24

5/(x(x-2)) =5/(6(4))= 5/24, good

x=6

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
