1. Rename the mixed numbers with common denominators
2. Add the mixed numbers together to get 15 4/6
3. Subtract the sum from 26 to get 10 1/2
4. Since the only term left on the left is k so k=10 1/2
X = 37 degrees.
Sine and cosine are complementary, which means when they are added together, the equal 90. So, to find sine, subtract 53 from 90, to get x = 37.
Here is an image to show this.
I hope this helps!
X=8.5
190-5=185
185/-5=-37
-37-3=-34
34/4=8.5
A: From the graph, car B was traveling faster.
Because the line of car B is more steep than the line of car A.
B:
The lines cross at (2,80), this means that the two cars were traveling at the same distance (80 miles) at the same time (2 hours).
C:
Since the line passes through the points (0,0) and (2,80)
So the unit rate or slope is 40 mph.
The distance which car A traveled in the first four hours = 4x40= 160 mph
