Answer: 5

Step-by-step explanation:

3 1/4 + 1 3/4

First:

3 1/4 = 3*4/4+1/4 = 12/4+1/4 = (12+1)/4 = 13/4

Second:

1 3/4 = 4/4+3/4 = (4+3)/4 = 7/4

Then:

13/4 + 7/4 = (13+7)/4 = 20/4 = 5

puteri [66]

So we know 20% of the audience are teenagers, and there are 360 teenagers.

Therefore, 1/5 of the audience members were teenagers, and that means 1/5 of the audience members is 360.

Multiply it by 5 to get answer:

360 * 5 = 1800

The total number of audience members are 1800.

$\large\bf{\underline{To \:find }}$

How many students voted not to be in falcon ?

$\large\bf{\underline{Therefore }}$

40% of the total students voted not be in falcon

$\large\bf{\underline{Hence }}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎⟹ 40% of 595

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $= \frac{40}{100} \times 595$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $=2 \times 119$

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

jenyasd209 [6]

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
