What does 15 and 16 mean

1 answer:

7 0

Seems like a proportions problem
In 15, you have 3 boxes and your partner has 1. Total 4 boxes. Each represents 12/4=3 hours. So you have 3 boxes = 3*3=9 hours and your friend has 3 hours.

Same method in 16. You have 4 and your friend has 8

What multiplies to 378 and adds to -51

Oliga [24]

Your answer would be -9 & -42.

Here's why ...
(-9)*(-42) A negative times a negative equals a positive (378).
Now, -9-42=-51 & you add these because you have two negatives.

Hope this makes sense & helps you ! (:
