Find the difference in temperature between each 1000 feet:

From 1 to 2: 30 - 23.5 = 6.5

From 2 to 3: 23.5 - 17 = 6.5

From 3 to 4: 17 - 10.5 = 6.5

The temperature change is constant as it drops 6.5 degrees for every 1000 foot gain in elevation.

At 5,000 feet the temperature would be : 10.5 - 6.5 = 4

At 6,000 feet: 4 - 6.5 = -2.5

At 7,000 feet: -2.5 - 6.5 = -9

At 8,000 feet: -9 - 6.5 = -15.5

At 8,000 feet the temperature would be  -15.5 degrees.

Can someone please tell me if i am right?

Second one is correct, that is an identity.

Third one is a contradiction:
6x - 15 = 3 * (2x - 6)    ------>    6x - 15 = 6x - 18

Fourth one:
5x - 3 * (x - 4) = 2 * (x - 6) ---> 5x - 3x + 12 = 2x - 12 ---> 2x + 12 = 2x -12
So this is a contradiction as well.

The answer is a.) -27

subtract 11 from 38
27 keeps the negative sign because -38 is larger than 11
