alyssa has 4 boxes that contain a total of 30 seeds. Three of the boxes contain the same number of seeds. The fourth box contains the sum of the other 3 boxes. How many seeds are in each box

Box 1: 5

Box 2: 5

Box 3: 5

Box 4: 15

Step-by-step explanation:

the three boxes have the same number of boxes, it has 5 because 5+ 5 + 5 = 15.

so the fourth box will have 15 because that's the sum of the three boxes, 15 + 15 = 30.

Hope this helps!

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
