The temperature is 1 degree at sunrise. It is 8 degrees colder at sunset. What is the temperature at sunset?

-7 degrees

Step-by-step explanation:

You must subtract 8 from 1.

1 - 8 =

To subtract, add the opposite. The opposite of 8 is -8. To subtract 8 from 1, we add -8 to 1.

= 1 + (-8)

Now you need to add two numbers with different signs, one positive and one negative.

Rule for adding a positive number and a negative number:

1. Find the absolute values of both numbers. Remove the negative sign: you now have 1 and 8.

2. Subtract the smaller number from the larger number. 8 - 1 = 7

3. The answer has the same sign as the number with greater absolute value. The two numbers being added are 1 and -8. The absolute values are 1 and 8, respectively. 8 is greater than 1. 8 is the greater absolute value, and it is the absolute value of -8, so the answer has the same sign as -8, so the answer is negative. We already knew the number was 7, so the answer is -7.

= -7

-7 degrees

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
