To figure out how many revolutions Buddy goes in 1 minute, (60 seconds) we can use proportions

4 revolutions/11 seconds = x revolutions/60 seconds
When we cross multiply, (multiplying one numerator by the other denominator, and vice versa for the other numerator) we get
240 = 11x
divide both sides by 11 to get
21.81 = x
or 21 complete revolutions

-11 + 2r = 5r - 6 - 5
masha68 [24]

Answer:

x = 0

Step-by-step explanation:

First we need to move either 5r or 2r to the other side, in order to isolate the variable.

We'll move 5r, in this case, by subtracting it from 2r. Now we got: -11 - 3x = -6 - 5.

Next we subtract 5 from -6 to get

-11 - 3x = -11.

Now we can add 11 on both sides to get -3x = 0.

Finally divide by -3 to get x = 0.

Hope this helps :)
