How fast does a driven gear turn if it has 25 teeth (t) and is driven by a10-tooth driver gear (T) at 250 RPM?

vazorg [7]

Given:

The number of teeth = t = 25

The gear is driven by a 10-tooth driver gear (T) at 250 RPM

Let the speed = s

So, using the ratio and proportion

$\frac{25}{s}=\frac{10}{250}$

Solve for s:

$\begin{gathered} 10s=25\cdot250 \\ \\ s=\frac{25\cdot250}{10}=25\cdot25=625 \end{gathered}$

So, the fear will be driven by 625 RP

Step-by-step explanation:

Step 1: Define

9m - m + 3 = -2(m + 1)

Step 2: Solve for m

Combine like terms: 8m + 3 = -2(m + 1)
Distribute -2: 8m + 3 = -2m - 2
Add 2m on both sides: 10m + 3 = -2
Isolate m term: 10m = -5
Isolate m: m = -1/2
