Answer:
x = 10
Step-by-step explanation:
The marked angles are "alternate interior" angles, so are congruent.
(x° +20°) = (4x° -10°)
30 = 3x . . . . . . . . . . . . . . . divide by °, add 10-x
10 = x . . . . . . divide by 3
Answer:
The slope is 0
Step-by-step explanation:
There is no change in y values making the slope have a value of 0
<span>Average of any physical quantity is defined over an interval of time. Therefore, the average temperature for this case should be calculated as follows:
Average temperature = (final temp. - initial temp.) / total time
</span>Average temperature = (-24 - 0) / 4
Average temperature = -6°C
Hope this answers the question. Have a nice day.
Here is a photo of what I chose as my equivalent numbers (Red represents my work, blue represents which step comes next, and highlighter shows what the answer is). My reasoning that 1/2 and 5/10 are equivalent is because 5/10 divided by 5/5 is 1/2.
