Answer:
a) language
b) 2/15
Step-by-step explanation:
For the first part, you can start by making the denominators same
you take the LCM of 3 and 5 which is 15
Language books are now 10/15 since you multiply the nominator and denominator by 5
While science books are 3/15
10/15 : 3/15 making it obvious that language books are more
if the remaining are math books then
total books - (language + science books) = math books
10/15 + 3/15 = 13/15 (non math books)
15/15 - 13/15 are math books making 2/15 of them math books
6u + 3u = 18
9u = 18
u = 18/9
u = 2
Solve for x.
Minus 6 from both sides. I will look like this: 5x+6-6=-4-6. It now equals 5x=-10. Divide both sides by by 5. Now, x=-2
