What could be x and y?

Answers

X= 60 or (60, 0) and Y = 30 or (0,30)

Answer:

20 for both x and y

Step-by-step explanation:

if we substitute 20 for x, we get 2x20 which is 40.

If we substitute 20 for y, we get 4x20 which is 80.

80 plus 40 is 120.

Hence the answer is 20 for both x and y

Answers

Answer:

5/14

Step-by-step explanation:

The quotient of the given numbers 5 / 12 and 1(1/6) will be ( 5 / 14 ).

What is a quotient?

A quotient in mathematics is the amount created by dividing two numbers. The term "quotient" is used frequently in mathematics and is sometimes known as the integer portion of a division, a fraction, or a ratio.

Given fractional numbers are 5 / 12 and 1(1/6). The quotient will be calculated as below:-

Quotient = ( 5 / 12 ) ÷ ( 1 ( 1 / 6)

Quotient = ( 5 / 12 ) ÷ ( 7 / 6 )

Quotient = ( 5 / 12 ) x ( 6 / 7 )

Quotient = 5 / 14

Therefore, the quotient of the given numbers 5 / 12 and 1(1/6) will be ( 5 / 14 ).

Answers

Answer:

0.07518

Step-by-step explanation:

First you set up the equation as:

0.537

x0.14

Then, you multiply the problem regularly. Your answer should be 007,518. Now, you add the decimal. My trick to remember this is that in the number 0.537, there are 3 digits after the decimal, so you get the number 3. In the number 0.14, there are 2 digits after the decimal. You get the number 2. You add together the 3 and 2 to get 5. In your number 007,518 place the decimal like this...

The decimal is here right now: 007518.

You move the decimal to the left 5 places: 0.07518

And you have your answer! I hope this helped!
