What's a rational number between 8 and 8.1

Answers

A rational number is any number that can be written in a/b form (like a fraction). So it just can't be a repeating decimal like how pie goes on forever. So let's see. 8.05 could work. Since you could write that as 8.05 over 1 (8.05/1)

The rational number between 8 and 8.1 is 8.05 / 1 or 16.1 / 2.

What is Number system?

A system of writing to express the number is called number system.

Given that;

The numbers are,

⇒ 8 and 8.1

Now,

Find the rational number between 8 and 8.1 as;

The rational number = (8 + 8.1) / 2

                                = 16.1 / 2

                                = 8.05 / 1

Thus, The rational number between 8 and 8.1 is 8.05 / 1 or 16.1 / 2.

Write an equation for each line. y intercept of -2.1, x intercept of 3.5

Answers

the answer should be:
y=3.5x-2.1

The equation of a line with given x and y intercept is y=0.6x-2.1.

What is a x-intercept?

The x-intercept for any curve is the value of the x-coordinate of the point where the graph cuts the x-axis, or we can say that the x-intercept is the value of the x-coordinate of a point where the value of y-coordinate is equal to zero.

Given that, y intercept is -2.1 and x intercept is 3.5.

Here, the coordinates are (0, -2.1) and (3.5, 0)

Now, slope m=(0+2.1)/(3.5-0)

= 2.1/3.5

= 0.6

Substitute m=0.6 and c= -2.1 in y=mx+c, we get

y=0.6x-2.1

Therefore, the equation of a line is y=0.6x-2.1.

ten less the quotient of a number and 3 and is 6

Answers

"Ten less" means that we subtract 10.  "Quotient" means that we divide.  
(x / 3) - 10 = 6   I can show you how to solve for x.   Add 10 on both sides of the equation.   x / 3 = 16   Multiply both sides of the equation by 3.   x = 48
I hope I helped :)
Final answer:

The question is about solving the algebra equation derived from the statement 'Ten less the quotient of a number and 3 is 6'. The equation is x/3-10=6 and through algebraic operations, we find that the solution is x = 48.

Explanation:

The subject of your question is Algebra, which is a branch of Mathematics. From your question, 'Ten less the quotient of a number and 3 is 6', we can write the algebraic equation. First, 'the quotient of a number and 3' is represented as x/3. Then, 'ten less' means we subtract 10 from the result. Lastly, 'is 6' means equals to 6. Therefore, the equation is: x/3 - 10 = 6.

To solve this equation, first of all, you should deal with the subtraction by adding 10 to both sides of the equation, which gives you x/3 = 16. Secondly, you then get rid of the fraction by multiplying both sides by 3, which yields x = 48. Hence 48 is the solution to your algebraic equation.
