Answer:

It is 32:200 for the 2nd row last one                        

Answer:

No solutions

Step-by-step explanation:

-3(6 - 2x) + 23 = 4 - 1/3(-18x - 2)

~Distribute both sides

-18 + 6x + 23 = 4 + 6x + 2

~Combine like terms

5 + 6x = 6 + 6x

~Subtract 5 to both sides

6x = 6x + 1

~Subtract 6x to both sides

0 = 1

Best of Luck!

Step-by-step explanation:

DISTANCE BETWEEN TWO POINTS

We want to firstly assume that the the three trees lies on the same line

so tress A,B and C are on the same line

Given

The direct distance between A to B= 200 ft

The direct distance between B to C= 300 ft

hence A to C= 200+300= 500ft

let us do a graphical representation for better understanding

A----B-----------C

200ft    300ft

A---------- -----C

       500ft

A to C= 500ft

Answer:

Between 100 and 500

Step-by-step explanation:

A to B is 200

And b to c is 300

A to C =500

200-300=100

Answer = Between 100 and 500

Step-by-step explanation:

This are the options:

A. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 4 equal parts.

B. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 8 parts.

C. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 5 equal parts.

D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.

Amount of Fabric owned by Louisa = 4 yards

If she uses 2/5 yards to make a doll dress, to get the number of dolls that 4 yards can make we will say:

1 doll = 2/5 fabric

x doll = 4 fabrics

Cross multiply

2/5 * x = 4*1

2x/5 = 4

cross multiply

2x = 20

Divide both sides by 2:

2x/2 = 20/2

x = 10

This means that she can make 10 dolls using 4 yards of fabric.

Hence the correct option will be

D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.

Answer:

A. The equation of the line is y=−2.5x+10.

C. The y-intercept is k.

F. The value of k is 10.

Step-by-step explanation:

A line passes through points (0, k) and (4,0) and has a slope of –2.5. Which statements are true regarding the graph of the line?

A. The equation of the line is y=−2.5x+10.

B. The equation of the line is y=−2.5x.

C. The y-intercept is k.

D. The y-intercept is 4.

E. The value of k is 4.

F. The value of k is 10.

Solution:

The slope of a line is the ratio of the vertical change to the horizontal change. The slope (m) of a line passing through [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Given that the line passes through (0, k) and (4,0)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]-2.5=\frac{0-k}{4-0}\\\\-2.5=\frac{-k}{4}\\\\k=10[/tex]

The equation of the line is given as:

[tex]y-y_1=m(x-x_1)\\\\y-10=-2.5(x-0)\\\\y = -2.5x+10[/tex]

The y intercept is the value of y when x = 0, hence intercept = k

Given the line that passes through points (0, k) and (4,0) and has a slope of –2.5, we need to get the value of "k

The formula for calculating the slope of a line is expressed as:

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\-2.5 = \frac{0-k}{4-0}\\-2.5=\frac{-k}{4} \\Cross \ multiply\\-2.5 \times 4 = -k\\-10 = -k\\k = 10[/tex]

Hence the value of k is 10.

From the coordinate given (0, 10) and (4, 0), we can see that the y intercept and x intercept of the graph is 10 and 4 respectively

Step-by-step explanation:

Since 2 1/2 cups of sherbet are needed to make 24 cups, and we need to make 12 cups of punch, it's basically 24 divided by 2. So we need to divide 2 1/2 by 2, which would be 1 1/4 cups.

A. 78.5m^2

Step-by-step explanation:

To find the area of a circle you have to do:

Area = πr^2

The diameter is 2.5 x 4 which equals 10 and radius is half the diameter, so 5. Now your equation would be:

Area = π5^2

Solve:

π x 5^2

5^2 = 5 x 5 = 25

π x 25

π ≈ 3.14

3.14 x 25 = 78.5

Answer:

π5^2 ≈ 78.5

Answer:

All real numbers.

Step-by-step explanation:

If both sides, when simplified, equals each other, the answer will be "all real numbers". Simplify the left side. Distribute 2 to all terms within the parenthesis:

2(x + 1) = (2 * x) + (2 * 1) = 2x + 2

2x + 2 = 2x + 2 ∴ A) All real numbers is your answer.

Explanation:

Pick any two rows from the table to form (x,y) points

I'll select the first two rows.

(x1,y1) = (-4,-3) from row 1

(x2,y2) = (0,-2) from row 2

Plug those values into the slope formula

m = (y2-y1)/(x2-x1)

m = (-2-(-3))/(0-(-4))

m = (-2+3)/(0+4)

m = 1/4

The slope is 1/4, which is also the rate of change.
