Answer:
e = 56
Step-by-step explanation:
Use cross multiplication.
28 * 14 = 7e
Simplify
392 = 7e
Divide each side by 7
e = 56.
Answer:
Y=15x
Step-by-step explanation:
<h2>Okay so let's approach this problem!</h2><h2 />
X is books and Y is total cost
Let's find the slope!
Y2-Y1/ X2-X1
Just replace


The slope is 15

Now replace x and y with coordinates and solve

The final equation:
y = 15x

Hi, thank you for posting your question here at Brainly.
This problem could be solved using the Law of Cosines, since we are given with the three sides. The equation goes,
b^2 = a^2 + c^2 - 2accosB. Substituting,
24^2 = 7^2 + 25^2 - 2(7)(25)cosB
Then B = 73.7 degrees. Therefore sinB or sin(73.7) = 0.96.
I think B should be the answer
