5 less than 3.1 times a number n plz help me

Answer:

no.

Step-by-step explanation:

Answer:

The first line shows the solutions to n > 0.

The open circle and shaded part after the 0 indicate that n > 0 is represented by the first line.

Answer:

It's the first one aka A.

Step-by-step explanation:

It's the first one bc it shows greater than. The second one shows n is = to or greater, 3rd one shows less than, and last one shows = to or lesser. So in other words, the correct answer would be A.

Answer:

y=x-2

Step-by-step explanation:

if you were to plot it onto a graph, the y intercept would be -2

Answer:

1/3 is the y intercept

Step-by-step explanation:

f(x) = -2/9x + 1/3

This is written in slope intercept form

y = mx+b where m is the slope and b is the y intercept

-2/9 is the slope and 1/3 is the y intercept

Answer:

The slope of the line that passes through the points M(-3, 5) and N(1, 8) in decimal form is 0.75

Step-by-step explanation:

The given points are M(-3, 5) and N(1, 8)

The formula for finding the slope, m, given the coordinates of two points on the line is given as follows;

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Where, (x₁, y₁) = (-3, 5), and (x₂, y₂) = (1, 8), we have;

[tex]Slope, \, m =\dfrac{8-5}{1-(-3)} = \dfrac{3}{4} = 0.75[/tex]

The slope, m = 0.75

The slope of the line that passes through the points M(-3, 5) and N(1, 8) in decimal form = 0.75.

Given:

Area of rectangle = [tex]6n^4+20n^3+14n^2[/tex]

Width of the rectangle is equal to the greatest common monomial factor of [tex]6n^4, 20n^3,14n^2[/tex].

To find:

Length and width of the rectangle.

Solution:

Width of the rectangle is equal to the greatest common monomial factor of [tex]6n^4, 20n^3,14n^2[/tex] is

[tex]6n^4=2\times 3\times n\times n\times n\times n[/tex]

[tex]20n^3=2\times 2\times 5\times n\times n\times n[/tex]

[tex]14n^2=2\times 7\times n\times n[/tex]

Now,

[tex]GCF(6n^4, 20n^3,14n^2)=2\times n\times n=2n^2[/tex]

So, width of the rectangle is [tex]2n^2[/tex].

Area of rectangle is

[tex]Area=6n^4+20n^3+14n^2[/tex]

Taking out GCF, we get

[tex]Area=2n^2(3n^2+10n+7)[/tex]

We know that, area of a rectangle is the product of its length and width.

Since, width of the rectangle is [tex]2n^2[/tex], therefore length of the rectangle is [tex](3n^2+10n+7)[/tex].

Answer:

Step-by-step explanation:

4.2) 2z² - 3z² = -z²

8x - x = 7x

4.3)  3x² - 4x²  = (3 -4)x² = -x²

    4z² - 3z²  = (4- 3)z² = z²

z² - 2z² = (1 - 2)z² = -z²

3x - x = 2x

Cannot be subtracted.

3y² - 3y² = 0

4.3) 2xy - x y                =  xy

      x²y² - 4x²y²           = -3x²y²

     x - y                        = /

   2x²y² - 6x²y²            = -4x²y²

  4xy  - 2xy                  = 2xy

4.4)  5xy - xy   = 4xy

       x²y² - 3x²y²  = -2x²y²

     3x³y - 2yx³  = x³y

Answer:

-6y=x

Step-by-step explanation:

3x+6y=2x=5y

Subtract 5y from all

3x+y=2x-5y

subtract y and 2x from both sides

x=-6y

Answer:

B

Step-by-step explanation:

We know that it costs 37 cents to mail a letter that weighs 1 oz or less. This would mean that for x ≤ 1, P(x) should equal 37. Already, we can eliminate A and D.

We also know that it costs an additional 26 cents for at most another ounce added to the original 1 ounce. This means that for 1 < x ≤ 2, P(x) = 26 + 37 = 63. This is shown by B.

Thus, the answer is B.

Answer:

10

Step-by-step explanation:

you use the Pythagorean theorem which you do 24^2 + b^2 = 26^2 you should have 576+b^2=676 then subtract 576 on both sides b^2=100 then sqre root which leaves you with b=10

Answer:

7/4

Step-by-step explanation:

its 7/8 because if it goes down 1/8 each day count that for 2 weeks which is 14 days so it would be 14/8 or 7/4

HOPED THIS HELPED!!!!!!! :D

The total change in depth of the water during this time period is 7/4 in

To subtract means to take away from a group or a number of things.

Given that, the depth of water in a swimming pool decreases by 1/8 inch per day do to evaporation, no water is added to the pool for a two week.

The reduce in the pool in 1 day is 1/8 inch.

So, for 2 weeks, it's 14 days, therefore, in 14 days it will reduce = 1/8x14 = 7/4 in

Hence, The total change in depth of the water during this time period is 7/4 in

Answer:

98 yards

Step-by-step explanation:

The new width is 40 yds + 2 yds = 42 yds.

Area = L × W

4200 square yds = L × 42 yds

L = 4200 yds ÷ 42 yds = 100 yds

The new length is 100 yds.

The old length = the new length - the width of the path × 2 = 100 yds - 1 yd × 2 = 100 yds - 2 yds = 98 yds.

The length of the park was 98 yds, before the path was built.

Answer:

98 yards

Step-by-step explanation:

First we will list our values

new w: 42

old w: 40

old l: x

new l: x+2

we are adding 2 to the new values as there is 1 yard on either side

now we will find the new area:

42 * (x+2) =4200

42x+84=4200

42x=4116

x=98

Answer: 0.667 kilograms

Step-by-step explanation:

From the question, we are informed that in a bag full of beans and rice, the ratio by weight of beans to rice is 2 to 9.

If the bag has a total weight of 3 kilograms, the amount of kilograms of beans that are there in the bag will be:

= 3/9 × 2 kilograms

= 6/9 kilogram

= 0.667 kilograms

Answer:

On 4/5 gallon of gasoline, hybrid car will travel 36 miles of distance.

Step-by-step explanation:

Suppose, non hybrid car travel "x" distance in 1 gallon of gasoline

then, hybrid will travel " 1 4/11* x" distance in 1 gallon of gasoline

Given that, non hybrid car travel, x = 33 miles per gallon

Then, hybrid car travel, 1 4/11*x = 1 4/11* 33 = 45 miles per gallon

On 1 gallon of gasoline hybrid car travel= 45 miles

On 4/5 gallon of gasoline hybrid car will travel= 4/5*45= 36 miles

On 4/5 gallon of gasoline, hybrid car will travel 36 miles of distance.

Red line arrives every 4 minutes

Blue line arrives every 5 minutes

Yellow line arrives every 6 minutes

All three just arrives at the train station ; when next will they all arrive at the train station at the same time.

Obtain the lowest common multiple of each arrov time :

Lowest common multiple of 4, 5, 6
