1. Describe a situation that fits each equation. Describe more than one situation for each equation, if possible.
a) 4x – 1 = 19
b) 2x - 4 = 10
2. Choose one of the situations above, and use a different equation to describe the same situation

Answer and Explanation: (P.S. If this helps you please help me by following me on IG: anxme.vxbez)

When the wheel rotates one revolution the point of the rim will travel a distance which is equal to circumference of the wheel circle.

Distance travel for one revolution = 2pir

Distance travel for one revolution = 2pixx10 = 20picm

The wheel rotates 5 revolutions per minute. So the distance travel by the point will be 20pixx5 = 100pi .

For one minute(60 seconds) the point travels 100picm distance.

So distance travelled in 2 seconds = 100pixx2/60 = 10.47cm

So the answer is 10.47cm.

Note:

Here we have to assume that the wheel rotates at a constant speed.
