Answer:
(f◦g)(x) = x
Step-by-step explanation:
The composition (f◦g)(x) means f(g(x)). As with any function evaluation, put the argument where the variable is, and simplify.
[tex](f\circ g)(x)=f(g(x))=f\left(\dfrac{3x}{x-1}\right)=\dfrac{\left(\dfrac{3x}{x-1}\right)}{\left(\dfrac{3x}{x-1}\right)-3}\\\\=\dfrac{\left(\dfrac{3x}{x-1}\right)}{\left(\dfrac{3x-3(x-1)}{x-1}\right)}=\dfrac{3x}{3x-3x+3}=\dfrac{3x}{3}\\\\\boxed{(f\circ g)(x)=x}[/tex]

Janice NEEDS 3 GALLONS of lemonade for a party. She has 4 quarts, 6 pints and 4 cups of lemonade already made. How many CUPS of lemonade does Janice have? Be sure to re-state the question when giving your answer.
Answers
Answer:
32 cups
Step-by-step explanation:
To find the total number of cups, we have to convert the measures that are not in cups to cups and add
1 quart = 4 cups
4 quarts = 4 x4 = 16 cups
1 pint = 2 cups
6 pints = 2 x 6 = 12 pints
total number of cups = 16 + 12 + 4 = 32 cups

Step-by-step explanation: The first answer is c. 7+3w, because the puppy already weighs 7 ounces. Since the puppy didn't end up losing those pounds, then you would add instead of subtract. Since the puppy gains 3 ounces a week, you would multiply the 3 ounces by the number of weeks that pass by. So, if one week passes, the puppy gains three ounces. Add that to the original 7 ounces, then after one week, the puppy weighs 10 ounces.
The second answer would be a. 22 ounces, because if you use the previous formula (x=7+3w), then you would plug 5 in for w. This would give you 7+3(5). 3x5=15 and 15+7=22. therefore, x=22 ounces.
Answer:
7)c, 8)a
Step-by-step explanation:
since it is originally 7 oz, and grows 3 ounces a week, it would be 7+3w.
Substitutions would be 7+3(5) = 7+15 = 22 oz

what is 78 ÷ 5 and the remainder
Answers
Answer:
The answer is: (15) and the remainder is (6)
~i really hope this helps, have a gr8 day my friend!~
Step-by-step explanation:
Answer:
Step 1) Start by dividing 78 by 5 to get the decimal answer as illustrated below. Note that we round the answer if necessary, but don't worry, the final answer will still be exact.
78 / 5 = 15.60
Step 2) Next we take the Whole part of the answer in Step 1 and multiply it by the Divisor. As you can see, it does not matter if we rounded in the previous step because the Decimal part is ignored. Furthermore, the Divisor in 78 divided by 5 is 5. Thus, the Whole multiplied by the Divisor is:
15 x 5 = 75
Step 3) Finally, we will subtract the answer in Step 2 from the Dividend to get the answer. The Dividend in 78 divided by 5 is 78. Thus, our final calculation to get the answer is:
78 - 75 = 3
That is all there is to it! Again, the answer is 3.
So here
78 ÷ 5 is 15.6 and it's remainder is 3

senior senator can work his way through a
bureaucratic labyrinth in 30 minutes.
Working together, how many minutes would
it take them to work their way through 12
bureaucratic labyrinths?
Answers
-- Working together, they work through (1/50 + 1/30) of a labyrinth in 1 minute.
-- That's 1/18.75 of a labyrinth each minute.
-- So it takes them 18.75 minutes to work through 1 labyrinth together.
-- To work their way through 12 labyrinths, working together, would take them
(12 x 18.75 minutes) = 225 minutes.
