Samuel and Leticia are playing a game. After the first round of the game, Samuel's score was -19 and Leticias score was 21. The
Hoochie [10]

Answer: Leticia won the first round

==============================================================

Your teacher is basically asking "which value is further from zero on the number line?". The value -19 is 19 units away from zero; while 21 is 21 units away from zero.

See the attached image below. Each "space" is a distance of 1

Absolute value measures distance along the number line. Distance is never negative. In terms of notation, you would say

|-19| = 19 and |21| = 21

The outputs 19 and 21 are then compared. We see that 21 is larger, so therefore, Leticia has the higher score and she won the first round.

A casino riverboat travels up the Mississippi Rive at 12 mph and then back to its original port at a rate of 15 mph. The round t
o-na [289]

Speed up to Mississippi Rive = 12 mph

Speed back to original port = 15 mph

Total time taken by the riverboat = 7.5 hours

Total distance covered = ?

We know that the distance covered each side would be the same.

So Distance up to Mississippi Rive = Distance back to original port

⇒ {\text} Speed up to Mississippi Rive * Time taken to reach Mississippi Rive = Speed back to the original port * Time back to the original port .......... (i)

Let Time taken to reach Mississippi Rive = x .............. (ii)

⇒ Time taken to reach back to original port = 7.5 - x .......... (iii)

Substituting (ii) and (iii) in (i)

⇒ {\text} 12 * x = 15 * (7.5 - x)

⇒ {\text} 12x = 112.5 - 15x

⇒ {\text} 27x = 112.5

⇒ {\text} x = [tex]\frac{112.5}{27} [/tex]

Using value of x to determine distance traveled:

Distance Traveled up to Mississippi Rive = {\text}Speed up to Mississippi Rive * Time taken to reach Mississippi Rive

⇒ Distance Traveled up to Mississippi Rive = {\text}12 * \frac{112.5}{27}

⇒ Distance Traveled up to Mississippi Rive = 50 miles

Hence, the riverboat traveled total of 50 + 50 = 100 miles
