For 7: because of the decimal place in the 0.6 it's not a huge number and it's not possible to get a big number like 15000

3 / 5 = (x+1) / (y-2)
↓
↓ multiply by 5 / 3
↓
1 = 5 * (x+1) / 3 * (y-2)
↓
↓ move and simplify
↓
5x + 5 = 3y - 6
↓
↓ minus 5
↓
5x = 3y - 11
↓
↓ divide by 5
↓
Answer : x = (3y - 11) / 5
Answer:
B: 12
Step-by-step explanation:
1 cookie without nuts + 3 cookies with nuts = 4 cookies
1 cookie without +3 cookies with = 4 cookies
1 cookie without + 3 cookies with = 4 cookies
1 cookie without + 3 cookies with = 4 cookies
4+4+4+4=16
1 cookie without + 1 cookie without + 1 cookies without + 1 cookie without = 4 cookies without.
16 cookies total -4 cookies without=12 cookies with.
12 cookies have the nuts
