(-----×1/4)÷6×3/9 I need the step to this problem so that I explain to my grandson how he he gets the answer
lesya692 [45]

Answer:

-----×1/72

Step-by-step explanation:

The <em>order of operations</em> says do these operations in order left to right. Please note that ÷ means the same as / unless you define it otherwise in your problem statement.

If you intend the ÷ symbol to be used to indicate everything to its left is divided by everything to its right, it is appropriate to use parentheses for that grouping, as in ...

  (-----×1/4)÷(6×3/9) = (-----×1/4)÷2 = -----×1/8

_____

Here, we're going to evaluate what you have written according to the usual rules as described above.

  (-----×1/4)÷6×3/9 = -----×1/24×3/9 = -----×(3/24)/9

  = -----×1/8/9

  = -----×1/72

_____

<em>Comment on the arithmetic</em>

Fractions are multiplied and divided in the usual way:

  a/b×c = (a×c)/b

  a/b/c = (a/b) × (1/c) = a/(b×c)

___

<em>Comment on fractions and parentheses</em>

Please note that parentheses are required on any numerator or denominator that consists of anything other than a single number or variable. (The exception is the case where the numerator is a product, because a·b/c = (a·b)/c with or without the parentheses.)

Answer:  y = -x/3 + 5

Step-by-step explanation:

What we know:

- Our points are (-3, 6) and (0, 5)

First, we need to find the slope. The formula for finding slope is y2 - y1/x2 - x1.

Now, we need to plug in our values.

5 - 6/0 - (-3)

Solve.

-1/3

Our slope is -1/3.

But now we need to find the y-intercept. To do this, we will use the equation y = mx + b.

You can use either coordinate pair, but I will be using (-3, 6) first.

Plug in the values.

6 = -1/3(-3) + b

Simplify.

6 = 1 + b

Subtract 1 to both sides.

6 - 1 = 1 - 1 + b

5 = b

The y-intercept is 5. Now we can put everything together!

y = -1/3x + 5

y = -x/3 + 5

For the coordinate (0, 5), you do the same thing.

5 = -1/3(0) + b

5 = 0 + b

5 = b

y = -1/3x + 5

y = -x/3 + 5

Line m passes through the points (3, 7) and (6, 12) while line n passes through the points (-5, 1) and (-2, 6). Which statement
vodomira [7]

Hey there! I'm happy to help!

First, let's find the slope of the two lines. To find the slope, you divide the difference in the y-values by the difference in the x-values.

LINE M

7-12/3-6=-5/-3= <u>5/3</u>

LINE N

1-6/-5+2=-5/-3=<u>5/3</u>

If lines have the same slopes, they are parallel because they are always moving at the same incline and therefore will never meet. This matches what answer A says.

Therefore, the correct answer is A) Lines m and n have the same slope so they are parallel.

I hope that this helps! Have a wonderful day!
