Answer:
3.5 Grams
Step-by-step
set 2grams/60lbs equal to xgrams/105
x representing the amount of medicine needed for a 105lb child
Then you divide 60 by 105.
60/105=1.75
Now you multiply 2 by 1.75.
2 x 1.75 = 3.5
3.5 is your answer because 105 is 1.75 times more lbs than 60lbs
meaning you would need 1.75 times the amount of 2grams
to determine the value of x, which is 3.5grams
$40+$35=$75
75/100*8.75=6.5625
6.5625+75=81.5625
approximately equal to $81.56
The answer for the coke one is 46cents because you would do 2.76 divided by 6 and then for the marathon it would be 6.55 because u do 26.2 divided by 4 and get 6.55 hoped this helped
The answer is 2^27 because the 2 is supposed to stay the same and 9*3=27.
Hope this helped☺☺
