You might also want to consider that it's negative because it's BELOW sea level. If you are going down, that wount mean that it is negative. So after mltiplying and turning the result into a proper fraction, you get A as your final answer.
A: Commutative Property of Addition
Answer:
x=10
Step-by-step explanation:
The answer is 13.
To solve this question, you need to determine the slope of the function. if howl is y and the temperature is x of the graph, the slope would be:
9-5/(40-70)= 4/-30= -2/15
Using one of the point and the slope, you can find the number of howl
-2/15= 9-y/40-(-20)
9-y= -2/15 * 60
9-y= -4
y= 9+4= 13
Answer:
The greatest common factor is 1
Step-by-step explanation:
The factors of 4 are: 1, 2, 4
The factors of 6 are: 1, 2, 3, 6
The factors of 45 are: 1, 3, 5, 9, 15, 45
