A water pipe is 3 feet below the ground. A gas pipe is 8 feet below the ground. Which pipe is higher? EXPLAIN YOUR ANSWER

The water pipe
3 feet is less than 8 feet so if you go down 8 feet it would be deeper than 3 feet making the water pipe higher.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
