The equation is y=2.5x.
Let the y axes increase by 2.5 and the x axes by ones
Answer:
B. 40
Step-by-step explanation:
Given:
The given shape is nonagon.
It consist of 9 sides.
We need to find the value of exterior angle 'x'.
Solution:
Now we know that;
"The sum of the exterior angles of any polygon is 360 degrees."
Therefore to find the measure of one exterior angle of any regular (all angles are congruent) polygon, divide 360 by the number of angles.
Since here there is Nonagon then there would be 9 exterior angles.
So measure of angle 'x' = 
Hence The value of 'x' 40°.
Answer: C
Step-by-step explanation:
I did that problem just a second ago
The two friends will be 150 miles apart, when the sum of the distances covered by the them is 150 miles.
distance = speed x time.
Let the time covered when they are 150 miles apart be x, then:
40x + 35x = 150
75x = 150
x = 150/75 = 2.
Therefore, the two friends will be 150 miles apart in 2 hours.
