We'll start by calling the number of pigeons we started with x, because it's the unknown.

After she clapped 1/3 flew away so she was left with

(1 - 1/3) x = (2/3) x

Two flew back, so now there are

(2/3) x + 2

She clapped again and half left, half stayed, so now

(1/2) ( (2/3) x + 2 )

One came back and there were five,

(1/2) ( (2/3) x + 2 ) + 1 = 5

Solving is unraveling.

(1/2) ( (2/3) x + 2 )  = 4

(2/3) x + 2   = 8

(2/3) x  = 6

x = (3/2) 6 = 9

Answer: 9 pigeons

Check: Reviewing the story,  9 -> 6 -> 8 -> 4 -> 5 good

Which two terms in (3+14) +27 could you add to get a multiple of ten? ​
Aleksandr-060686 [28]

Answer:

3 and 27

Step-by-step explanation:

<u>Step 1:  Determine which two terms we can use</u>

We have the following numbers to choose from:  3, 14, 27

Adding two numbers to get a multiple of ten means that the number that we come up with needs to be divisible by ten.  For example:  20, 30, 50, 100 are all multiples of ten.

In this example the only one that would add up to create a multiple of ten is 27 and 3 which would give us 30 which is a multiple of 10.

Answer: 3 and 27
