Answer:
y = 4 and x = 12
Step-by-step explanation:
Step by step explanation in the pic. Atleast the way I did it.
The cost of one book = $ 6 7
Number of books = 1 0 2
The cost of 102 books = $ 67 × 102
= $ 6834
Therefore, cost of 102 books = $ 6834
Cos (A-B) - cos (A+B)
= (cosAcosB +sinAsinB) - (cosAcosB - sinAsinB)
=2sinAsinB
Ans: 4
Answer:
2:1
Step-by-step explanation:
because 60 split in half is 30
and 30 split in half is 15
then if you divide both numbers by 5 then you get 6:3
6:3 is equivalent to 2:1
sorry im a little late, hope this helped though.
<em>you just add 8 + 8 + 8 it equals </em><u><em>24. rounded it will be 20</em></u>

<u><em>im pretty sure thats how you do it if not sorry</em></u>
