3a+5b/3c-5d =3a -5b/3c- 5d​

Mathematics
1 answer:

5 0

Answer:

-30bc + 50bd

Step-by-step explanation:

3a + 5b/3c - 5d = 3a - 5b/3c - 5d

(3c - 5d)(3a - 5b) = (3a + 5b)(3c - 5d)

9ca - 15bc - 15da + 25db = 9ac - 15ad + 15bc - 25bd

9ca -15bc - 15da + 25db - 9ac + 15ad - 15bc + 25bd

9ca and -9ac and -15da and 15ad cancel each other out, so

-30bc + 50db is left

At a charity fundraiser, each female attendant donated $1,200 and each male attendant donated $800. If the average donation at t
Flauer [41]

The ratio of the number of female attendants to the number of male attendants is 21/17

<h3>Ratio</h3>

  • Amount donated by female attendant = $1200
  • Amount donated by male attendant = $800
  • Average donation = $900

let

  • number of female attendant = x
  • number of male attendant = y

900 = 1200x + 800y / (x + y)

900x + 900y = 1200x + 800y

900x + 1200x = 800y + 900y

2100x = 1700y

x : y = 2100 / 1700

x : y = 21 ; 17
