Answers

Answer 1

Answer:

[tex]\boxed{\sf x=-3\frac{3}{20}}[/tex]

Step-by-step explanation:

[tex]\sf -4\cfrac{2}{5}=x-1\cfrac{1}{4}[/tex]

Multiply Both sides by 20, Which is the LCM of 5, 4:

[tex]\mapsto \sf (4\times 5+2)=20x-5(4+1)[/tex]

Multiply 4 and 5= 20, and add 20 +2 =22

[tex]\mapsto \sf -4\times 22=20x-5(4+1)[/tex]

Multiply -4 * 22 = -88, and then add 4+1=5:

[tex]\mapsto \sf -88=20x-5\times 5[/tex]

Multiply -5 *5 = -25:

[tex]\mapsto \sf -88=20x-25[/tex]

Now, swap sides:

[tex]\mapsto \sf 20x-25=-88[/tex]

Add 25 to both sides:

[tex]\mapsto \sf 20x=-88+25[/tex]

[tex]\mapsto \sf 20x=-63[/tex]

Divide both sides by 20:

[tex]\mapsto \sf x=\cfrac{-63}{20}[/tex]

Now, convert an improper fraction to a mixed number: →

[tex]\mapsto \sf x= -3\cfrac{3}{20}[/tex]

What is the categorization

Categorization is the process of classifying or grouping items, data, or concepts into specific categories or classes based on their shared characteristics or attributes

This variable shows different types of shirts (long sleeves with a collar, long sleeves without a collar, short sleeves with a collar, or short sleeves without a collar).

The nominal level of measurement is the basic level where data is placed into separate groups without any particular order or ranking.

Answer:

The train appears to go the same distance each minute

9mins

The cost for each person appears to be the same

Step-by-step explanation:

So for the first qu you basically want to find the distance the train travels each minute, so for

3mins : 9km

therefore

1min : 3km

basically divide 9 by 3

then the train travels 27km, how long does it take?

if 3km = 1min

then 27/3 = 9

so it takes the train 9 minutes

Then for the second qu you'll do the same thing

2ppl : $16

so one person : 16/2

so 1 person costs $8

so for 8 ppl you multiply 8 by 10

8ppl : $80

4.what equation passes through the 2 points
(2, 1) and (6, 9)

Answers

Answer:

y = 2x - 3

Step-by-step explanation:

Finding the slope:

[tex]\frac{y2-y1}{x2-x1}[/tex]

= (9-1)/(6-2)

= 8/4

= 2

Slope: 2

Substituting this value into the equation 'y=mx+c':

y = 2x + c

Substituting any points (in this case, (2,1)) into the above equation:

1 = 2(2) + c

1 = 4 + c

c = 1 - 4

c = -3

Hence,

y = 2x - 3

Hope this helps and be sure to have a wonderful time ahead at Brainly! :D

Answer:

y=2x-3

Step-by-step explanation:

first put in the equation:

[tex]\frac{9-1}{6-2}[/tex] and you get 8/4 which equals 2. so this is your slop.

now put in this equation:

[tex]y-y_{1}=m(x-x_{1})[/tex]

so you put in (2-1)

[tex]y-1=2(x-2)[/tex]

and you get

y-1=2x-4

and if u add 1 to both sides you get y=2x-3

how many cubes with side length of 1/3cm does it take to fill the prism l=2 w=4/3 h=2

Answers

Given :-

Dimensions of cube = 1/3 cm *1/3cm *1/3cm.Dimensions of cuboidal prism = 2cm*4/3cm *2cm .

To Find :-

The number of cubes that can be filled.

Answer :-

The number of cubes will be say ' n ' ,

n = Volume of cuboid / Volume of cube n = 2cm*4/3cm *2cm ÷ 1/3 cm *1/3cm *1/3cmn = 2² * 4 * 3³ / 3 n = 16 * 9n = 144

Hence the number of cubes is 144.

3 2. Write the equation of a line that includes the point (-4, 0) and has a slope of 5 in slope-intercept form- 12 3 y=-=X-2 5 5 3 Y= -=X - 12 O 3 y=-=X-5 12 y=-=X+

Answers

Answer:

y= 5x+20

Step-by-step explanation:

Slope intercept form is

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

The slope is 5 and a point on the line is (-4,0)

Substituting this information into the equation, we can solve for b

0 = 5(-4) +b

0 = -20+b

Add 20 to each side

0+20 = -20+20+b

20 = b

y = 5x+20

[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]

Let's find the y - intercept (c) of the line, by Plugging the value of x and y from coordinates of the given point (-4 , 0) and slope (m) = 5 :

[tex]y = mx + c[/tex]

[tex]0 = (5 \times (- 4)) + c[/tex]

[tex]0 = - 20 + c[/tex]

[tex]c = 20[/tex]

now, let's plug the value of slope (m) and y - intercept (c) in general equation of line to find the equation of line will have been asked for.

[tex]y = mx + c[/tex]

[tex]y = 5x + 20[/tex]

C) 16 7/20

Step-by-step explanation:

The perimeter can be found by the formula:

Let P = perimeter,

P = 2 x (Length + Width)

P = 2 x (8 7/40)

P = 16 7/20 meters

Answer: k = -1

2m = -6 that means m = -3
You can tell by dividing -6 by 2 to get -3

Now we know m = -3 let’s put that in the equation

3(-3) - 4k = -5

-9 - 4k = -5

Just try the option you have to figure it out. You know it’s not -3.5 or 3.5 because it’s a whole number so it wouldn’t be anything that’s a decimal.

-9 - 4(1) = ?

-9 - 4 = 13

Now let’s try doing -1

-9 - 4(-1) = ?

-9 - -4 = -5

Point Fis on line segment EG. EG = 100, EF = 4x - 20, and FG = 2x + 30. Write an equation that you would use to solve for x, then state the value of x, and the length
of line segments EF and FG.

Answers

Step-by-step explanation:

Line segment = EG

point on a line segment = F

EG = 100

EF = 4x - 20

FG = 2x + 30

a/q, EF + FG = EG

the equation is

4x - 20 + 2x + 30 = 100

now solution for x is

→ 4x - 20 + 2x + 30 = 100

→ 6x + 10 = 100

→ 6x = 100 - 10 = 90

→ x = 90/6 = 15

therefore, value of x is 15.

and according to given information

EF = 4x - 20 = 4(15) - 20 = 60 - 20 = 40

FG = 2x + 30 = 2(15) + 30 = 30 + 30 = 60
