Set up a ratio:

5/3 = 40 / 2x+10

Cross multiply:

5(2x+10) = 3(40)

Simplify:

10x+50 = 120

Subtract 50 from each side:

10x = 70

Divide both sides by 10:

x = 70/10

x = 7

If the polygons are similar, then the top side is equal to one half of the left side.
Since side (x -1) = 8, then x = 9.

Dominik [7]

Answer:

There are 144 faculty at the college are certified

Step-by-step explanation:

- A local community college employs 240 full time faculty

∴ There are 240 full time employs

- Approximately 3/5 of the full time faculty are certified to teach online

∴ 3/5 of the total 240 are certified to teach on line

- We need to find how many faculty at the college are certified

To find that multiply the fraction of the certified by the total number

of the full time faculty

∵ The fraction of certified is 3/5

∵ The total of the full time faculty is 240

∴ The number of certified = $\frac{3}{5}$ × 240

∴ The number of certified = 144

There are 144 faculty at the college are certified
