Sarah's expression is correct because for every hour you get 9 dollars so 9(1) is 9 dollars for one hour. Then for two Hours it would be 9(2) which equals 18.
(8•365)•35 is the correct answer because 8 hrs of sleep each day times 365 days in a year = 2920 hrs slept in one year. Now you must take 2920 and multiply it by the 35 years she has been alive to get 102,200 hrs of sleep.
Answer:
$75.65
Step-by-step explanation:
$89 x .15 = $13.35
$89 - $13.35 = $75.65
For example, y = k/x; when x = 3 => k = 3y; when y = 9 => k = 27 and x = 27/9 = 3;
The answer is 3!
Answer:
r=56
Step-by-step explanation:
Since, r divided by 8 gives 7, if you do the inverse function(which is basically like the reverse of the question)
you can multiply 8 and 7 to find the r.
So 8 times 7 gives 56.
And to check you can do
which gives 7
You can tell me if my explanation is wrong. Thanks
