Answer:
175 mg/day
Step-by-step explanation:
It's a matter of units conversion. The conversion factors all have a value of 1 (the numerator is equal to the denominator), and all are chosen to cancel units you don't want and give units you do want.
Answer:
In arithmetic, variables look like letters.
Step-by-step explanation:
As we know that Mathematical arithmetic deals with numbers and certain properties with them.
Some of the main properties between numbers are as follows:
Variables do not remain constant, so we basically assign a number to a variable with an equal operator denoted by '='.
For example, let us assume a variable x being equal to 7. so it can written as:
Let suppose the value of the variable x=7 changes to x=10, then the new value will be:
Therefore, the correct answer is:
In arithmetic, variables look like letters.
Let x is the amount of $11 per pound coffee
then the equation will be,
11x + 3(30) = 5 (x + 30)
11x + 90 = 5x + 150
11x - 5x = 150 - 90
6x = 60
x = 10
So, $10 is the amount of $11 per coffee that should be added
