I believe the answer is b I think
Answer with explanation:
The equation, y=3 x,
y=Distance traveled
x =Total time
![\frac{\text{Distance traveled}}{\text{Time}}=\frac{y}{x}=3\\\\ \frac{dy}{dx}={\text{Rate of change}}={\text{Velocity}}=3 {\text{unit of time}]](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BDistance%20traveled%7D%7D%7B%5Ctext%7BTime%7D%7D%3D%5Cfrac%7By%7D%7Bx%7D%3D3%5C%5C%5C%5C%20%5Cfrac%7Bdy%7D%7Bdx%7D%3D%7B%5Ctext%7BRate%20of%20change%7D%7D%3D%7B%5Ctext%7BVelocity%7D%7D%3D3%20%7B%5Ctext%7Bunit%20of%20time%7D%5D)
Also, in terms of straight line
Slope =3= uniform Velocity
Point (3,9) and (5,15) represents Distance traveled in 3 (unit of time) =9 unit ,and 15 unit=Distance traveled in 5 (Unit of time).
→Alonso is moving with uniform speed=3 (unit of time), as velocity remains constant in the entire process.

6x=4x+16 (they are vertical angles
2x=16
x=8
4(8)+16+11y=180 (they form a straight angle together)
32+16+11y=180
48+11y=180
11y=132
y=12
36.
7x=56 (vertical angles are equivalent)
x=8
56+y+2(8)=180 (these three angles form a straight angle)
56+y+16=180
72+y=180
y=108
Hope this helps!
3a x 3=729
9a=729
--- -----
9 9
a=81
The number is 81.
Check: 3(81)x3=729
First step is to find R
use The equation QR =43
R=43/Q
now since we have R plug that into PR= 9x - 31
P(43\Q) = 9x - 31
P43/QP +31 =9x
9x=P43÷QP +31
x=P43÷QP+31 /9
Since the question doesnt specify to leave the question in terms of P or Q i suppose this is the final answer
Hope this helps! xD
would not mind if you put it as the brainliest answer
