Question

Please help ASAP I don't get it
Over a period of 6 hours, the temp rose 4°, then 3 more. It then dropped 2°, dropped 3° more. The temp at the end of the 6 hours was -5°. What was the starting temp?

Answer 1

Answer:

The answer is -7

Step-by-step explanation:

If you add 2 and then 3 to -5 you get 0. Take 4 and then 3 and you are left with -7

Answer 2

Answer:

-7 degrees

Step-by-step explanation:

-5 degrees at the end

Work backwards

so, if over 6hrs, it rose a total of 7 degrees and dropped a total of 5 degrees, by working backwards it'd be a rise of 5 and a decline of 7,

-5 + 5 = 0

0 - 7 = -7

now apply that to the beginning, if it was -7 degrees in the beginning and it raised by 4  = -3, then raised another 3 = 0, but then dropped 2 = -2, and dropped another 3 = -5

(This is what I have got, I hoped it helped)
