What is 3/7k = 12/35

Answers

Answer 1

Answer: $(3)/(7) k= (12)/(35)$

First. Lets divide those fraction so the problem is easier to work with.

0.42k=0.34

Now, divide both sides by 0.42 to get k by it's self.

You should get k=0.81

Answer 2

Answer: 3/7 * 4 = 12/35 (Is this what your asking for?)

A rational number can be written as the ratio of one blank to another and can be represented by a repeating or blank decimal

Answers

we know that

A rational number is the quotient of two integers with a denominator that is not zero , and can be represented by a repeating or terminating decimal.

Repeating Decimal is a decimal number that has digits that go on forever

Terminating decimal is a decimal number that has digits that do not go on forever.

examples

$(1)/(3) = 0.333...$ (the $3$ repeats forever)----> Is a Repeating Decimal

$0.25$ (it has two decimal digits)----> Is a Terminating Decimal

therefore

the answer is

A rational number can be written as the ratio of one $integer$ to another and can be represented by a repeating or $terminating$ decimal

A rational number can be written in the form:

$(p)/(q); \ called \ the \ ratio \n \n where \ p \ and \ q \ are \ whole \ numbers$

The number $q$ isn't equal to zero because the division by zero is not defined. So we can represent rational numbers by a repeating or terminating decimal, for instance in the following four exercises we have:

$(2)/(3)=0.6666...=0.\stackrel{\frown}{6} \n \n (5)/(8)=0.625000...=0.625\stackrel{\frown}{0} \n \n (3)/(1)=3.000...=3.\stackrel{\frown}{0} \n \n (3446)/(2475)=1.392323...=1.39\stackrel{\frown}{23}$

Match the pairs of polynomials to their products.

Answers

Answer:

Step-by-step explanation:

1) (xy+ 9y + 2) and (xy – 3)

Each term of second expression will be multiplied by first bracket.

xy(xy+9y+2) -3(xy+9y+2)

x²y²+9xy²+2xy-3xy-27y-6

x²y²+9xy²-xy-27y-6

2)(2xy + x + y) and (3xy2 – y)

3xy²(2xy+x+y) -y(2xy+x+y)

6x²y³+3x²y²+3xy³-2xy²-xy-y²

6x²y³ – 2xy² + 3x²y² – xy + 3xy³ – y²

3) (x – y) and (x + 3y)

x(x-y) +3y(x-y)

x²-xy+3xy-3y²

x²+2xy-3y²

4) (xy + 3x + 2) and (xy – 9)

xy(xy + 3x + 2) -9(xy + 3x + 2)

x²y²+3x²y+2xy-9xy-27x-18

x²y²+3x²y-7xy-27x-18

5) (x2 + 3xy – 2) and (xy + 3)

xy(x2 + 3xy – 2) +3(x2 + 3xy – 2)

x³y+3x²y²-2xy+3x²+9xy-6

x³y+3x²+3x²y²+7xy-6

6) (x + 3y) and (x – 3y)

x(x + 3y) -3y(x + 3y)

x²+3xy-3xy-9y²

x²-9y² ....

Answer: (xy + 9y + 2) and (xy – 3) —> x3y + 3x2 + 3x2y2 + 7xy – 6

(2xy + x + y) and (3xy2 – y) —> 6x2y3 – 2xy2 + 3x2y2 – xy + 3xy3 – y2

(x – y) and (x + 3y) —> (x + 3y) and (x – 3y)

(xy + 3x + 2) and (xy – 9) —> x2y2 + 3x2y – 7xy – 27x – 18

Ali says if two lines share a point they cannot be parallel do you agree explain

Answers

Yes, parallel lines do not touch each other ever.

How are parallel straight lines related?

Parallellines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.

Since the given parallel line has equation y = 2x + 2, thus its slope is 2 and thus, the slope of the needed line is 2 too.

We are given that Ali says if two lines share a point they cannot be parallel .

Horizontal refers to something that goes parallel to ground level. Of course it depends on from where you see that thing.

When you slice an object horizontally, you cut it parallel to ground.

We know that parallel linesdo not touch each other ever.

so that's make ali statement correct.

Yes, parallel lines do not touch ever, that's what makes them parallel.
