Write the phrase as an expression.Then evaluate when x=5 and y=20. The Quotient of 40 and the difference of a number y and 16.

Answers

For this case we have the following expression:

The Quotient of 40 and the difference of a number y and 16.

Writing the expression in algebraic form we have:

(40)/(y-16)

We observe that the expression does not depend on the variable x.

Therefore, substituting the value of y = 20 we have:

(40)/(y-16) = (40)/(20-16) = (40)/(4) = 10

Rewriting:

(40)/(y-16) = 10

Answer:

the phrase as an expression is:

(40)/(y-16)

For y = 20 the result is 10
Quotient is the answer in division. Difference is the answer in subtraction.

40
----------
( y - 16)


40                      40
---------------  =    ------------  =  10
(20 - 16)               4

To decorate a cake, you make a shade of purple icing using 2 drops of red food coloring for every 3 drops of blue. For 12 drops of red food coloring, how many drops of blue food coloring would you need?

Answers

18!
You would divide 12 by 2 since that's the number of red dots per blue. Then multiply by three and there's the answer!

Answer:

I think it would be 18

Step-by-step explanation:

Find the difference. express your answer in simplest form. (4r/s) - (r/s)

Answers

For this case we have the following expression:
 (4r / s) - (r / s)
 We observe that we have the term r / s in the whole expression.
 Therefore, we can draw common factor.
 Rewriting we have:
 (r / s) * (4-1)
 (r / s) * (3)
 3 (r / s)
 Answer:
 the difference is:
 3 (r / s)
your answer would be 4 because r/s - r/s would be 0 so you have 4 left hope this helps you!!!!
