Answer:
300
Step-by-step explanation:
you just divide the number of parts by minutes. In this case, 3600/12=300. There's your answer
B ($9.78)
9
777 rice balls
700700700 divided by 100100100 equals 7. 7 times 111 equals 777.
Here are my hints. You can solve it yourself
1/ xy = -12 --> x = -12/y
2/ (-12/y) + y = -1 --> -(12/y) + (y²/y) = -1 --> -12 + y² = -y --> y²+y-12=0
3/ From y²+y-12=0 we can find y then use y to find x and then do your
(x+3) * (y+3)
