What number produces a rational number when added to 1/3

Mathematics
2 answers:
Bingel [31]3 years ago
7 0

Answer:

1/2, 4/3, 1/2, ... any rational number

Step-by-step explanation:

The field of rational numbers is closed under the sum operation. Therefore, if a and b are rational numbers, the number (a + b) is also a rational number.

Consider the rational number a = 1/3, if we add it to any other rational number, the result of that sum will also be a rational number.

Examples:

1/3 + 1/2 = 5/6

1/3 + 4/3 = 5/6

1/3 + 1/6 = 1/2

tina drove 60 miles per hour to tucson. write a function rule that relates the number of miles traveled to the total of the hour
just olya [345]
A function rule would be y = 60x. Y represents the number of miles traveled, and X represents the number of hours. For example, if Tina drove for three hours, it would be 60×3 which is 180 miles.

One angle within a triangle is 76 degrees. What is the value of the exterior angle?
mrs_skeptik [129]

Answer:

The value of the exterior angle is 104\°

Step-by-step explanation:

we know that

The sum of the interior angle plus the exterior angle is equal to 180\°, because are supplementary angles.

Let

x-----> the measure of the exterior angle

so

76\°+x=180\°

solve for x

x=180\°-76\°=104\°

At Elisa's printing company, there are two kinds of printing presses: Model A, which can print 70 books/ day, and model B, which
Dmitrij [34]

Answer:

9 Model As.

Step-by-step explanation:

Let A represent Press A and let B represent Press B.

So, they own 14 total presses. This means that:

A+B=14

They can print 905 books per day, in other words, since A prints 70 per day and B prints 55 per day:

70A+55B=905

This is now a system of equations. Solve by substitution. From the first equation, subtract B from both sides:

A=14-B

Substitute this into the second equation: "

70(14-B)+55B=905

First, we can divide everything by 5 to simplify things:

14(14-B)+11B=181

Distribute the left:

196-14B+11B=181

Combine like terms:

-3B+196=181

Subtract 196 from both sides:

-3B=-15

Divide both sides by -3

B=5

So, the company has 5 Model B presses.

Which means that the company has 14-5 or 9 Model A presses.

And we're done!
