1 cup = 0.25 quarts,
12+15+5 = 32 cups:
32 * .25 = 8 quarts
-27 = 3x/10
Times 10 for both sides
-270 = 3x
x = -270/3
x = -90
Y=mx+b, checking the points,
Greenland's lowest temperature is -87 degrees while Africa's lowest is 76 degrees higher than that. That means we need to add 76 to -87.
Let T be the lowest temperature in Africa.
So the lowest temperature recorded in Africa is -11 degrees.
