Answer: 1,259 meters.
Step-by-step explanation:
GIven: The highest elevation in a small country occurs on a mountain above sea level = 1,232 meter
The lowest elevation in the same country occurs below sea level = -27 meters
The difference in elevation between the highest and lowest points = Highest - lowest
= 1232 - (-27) meters
= 1232+27 meters [ (-)(-)=(+) ]
= 1259 meters
Hence, the difference in elevation between the highest and lowest points = 1,259 meters.
It is given in the question that
Ann, Chang, and Kareem sent a total of 89 text messages over their cell phones during the weekend. Ann sent 9 fewer messages than Chang. Kareem sent 3 times as many messages as Ann.
Let number of messages Chang sent be x. And Ann sent 9 fewer than Chang, so Ann sent (x-9) messages. And Kareem sent 3 times as many messages as Ann, so Kareem sent 3(x-9) messages.
And the total messages are 89. That is

Combining like terms

So Chang sent 25 messages, Ann sent

And Kareem sent
