Use A: to find the value of x. In order to find that you would have to match one part of the proportion. x should be the numerator over 15 and 12 should be over 20 (The total length of that side of the triangle). Good luck. : )
If Sheila can ride her bike 6000 meters in 15 minutes, then you can divide
6000 ÷ 15 to find how far she can ride in 1 minute.
6000 ÷ 15 = 400.
So, Sheila can ride her bike 400 meters in 1 minute.
To find how many meters she can ride in 2 minutes, multiply 400 by 2.
400 x 2 = 800.
Sheila can ride her bicycle 800 meters in 2 minutes.
4^2 + 7^2 = c^2
This is because we know that the hypotenuse (c) is always diagonal to the right triangle, so the legs are 4 and 2 (a and b). There is your equation!
Good luck!
