The correct answer is B. The actual average high temperature for January is -3ºC.
Step-by-step explanation:
When we talk about temperatures in negative Celcius degrees (that is, below zero, which is the freezing point in this temperature scale), each temperature increase implies an approach to zero. Therefore, an increase of 4 degrees from -7ºC would reach a temperature of -3ºC, that is, numerically it would lower 4 levels, approaching 0.
Step-by-step explanation: Since one bag of trail mix contains 1/8 of a pound. You need to add how much it will take to make 2 pounds. So you keep adding 1/8 but the denominator stays the same each time you add. So it will look like this: 1/8 + 1/8 = 2/8 and you keep repeating it until you get 8/8 which equals 1 pound. Then you add 1/8 until you get 8/8 again. So 8 + 8 = 16.
Proportional reasoning is a form of mathematical reasoning that involves a sense of co-variation and of multiple comparisons, and the ability to mentally store and process several pieces of information. I hope my answer has come to your help. God bless and have a nice day ahead!
