Something + something = 48
something * something = -40

Hello there!

So, your question is

"something + something = 48"

and

"something * something = -40"

Since you didn't really give that much specific details, and you could correct me on this later, I'd say for the first one it's

47 + 1 = 48

As for the second one, it could be

-5 * 8 = - 40

OR

5 * -8 = -40

both ways are correct.

Hope this helps! If you have more instructions on this question, please let me know! Instructions are very important for MATH, cause even I mess up if the instructions are not clear. :)

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
