3. Solve the following problems. Reminder: Keep track of when you are dealing with part-to- part ratios and part-to-whole ratios. Be sure to show all work.
a. There are 50 teenagers at a swim meet. The ratio of locals to out-of-town
participants is 2:3. How many teenagers travelled from out-of-town to the swim
meet?

Out of town teenagers = 30

Step-by-step explanation:

Given that,

Total number of teenagers at a swim meet = 50

Let there are 2x locals and 3x out of town participants. The ratio of locals to out-of-town  participants is 2:3.

ATQ,

2x+3x = 50

5x = 50

x = 10

Out of town teenagers = 3x

= 3(10)

= 30

Hence, there are 30 teenagers travelled from out-of-town to the swim  meet.

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
