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.

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
