uysha [10]

Answer:


Step-by-step explanation:   emma's amount be X .  justin has $7.50+x because he has $7.50 more than emma.Since emma has 7.50+x-$12.to get everyones amount add what they have together which is=$7.50+x+$7.50+x-12 which in total is $63.00.after the calculations you get x=30.now distribute the x equally. so justin has $7.50+30=37.50.we also distribute it with emma's which is 7.50+30-12=25.5.

justin=$37.50

Emma=$25.50

to be sure add 37.50+25.50=$63

Ajay reads aloud from a sports magazine. He comes across the measurement 0.63 kilometer. How should he read this measurement alo
Mashutka [201]

Answer:

"sixty-three hundredths of a Kilometer"

Step-by-step explanation:

Decimal measurements are read based on the place of their digits. In this case, Ajay would read this measurement as "sixty-three hundredths of a Kilometer". This is because the final digit of the decimal form measurement is in the "hundredths" position. One more to the right and it would be in the "thousandths" while one more to the left would be the "tenths"

Will give brainliest to correct answer.

So, its time to do some MATH!

ok so i would first approach this problem by placing the prices in order from least to greatest......um it would look something like this...(cue the math skills in my brain)

1.29,1.59,1.99,2..09, and last but most definitely not least (get it?) 2.19

so basically the median is like the MIDDLE number of your data (shout out to my fellow middle children!)

and so you may be asking "how does one figure this out?" and i will tell you that it is quite simple...

so what you got to do is cross out a number from the left and a number from the right, and you will be left with one number, which is your middle number (or in fancy maths language -the median- that was supposed to be said with a British accent, so just bear with me there :-))

and so your final answer should be....(drumroll please)

$1.99 is your median 

(ta- da you are supermathematicalgeniuslevel smart)
