Answer:

Step-by-step explanation:

there is an obscure rule that looks like this

DB/AB = AB/CB

AB=40 for this problem

DB = x

CB = 20

then

X/40 = 40/20

X = 40(40/20)

X = 40(2)

X=80

I find that hard to believe too,   :D

but the rule says that's right

The ________________ is the horizontal number line on the coordinate grid.

Answers

Answer:

x-axis

Step-by-step explanation:

The horizontal number line is called the x-axis. The vertical number line is called the y-axis. The point where the x- and y-axes meet is the origin.

Hope this helps! <3

The x-axis is the horizontal number line on the coordinate grid.

It is one of the two axes that form the Cartesian coordinate system, used to locate points in a two-dimensional plane. The x-axis runs horizontally from left to right, intersecting with the vertical y-axis at the origin (0,0). It acts as a reference line, assigning numerical values to the horizontal position of points on the grid.

The x-axis allows us to specify the x-coordinate of a point, which represents its horizontal distance from the origin. Positive values are to the right of the origin, while negative values are to the left. By combining the x-axis with the y-axis, we can precisely define the position of any point in the coordinate plane.

solution to 5y\9-y\9 is equal to 8\9?​

Answers

Answer:

[tex]y = 2[/tex]

Step-by-step explanation:

1) Simplify 5y/9 - y/9 to 4y/9.

[tex] \frac{4y}{9} = \frac{8}{9} [/tex]

2) Multiply both sides by 9.

[tex]4y = \frac{8}{9} \times 9[/tex]

3) Cancle 9.

[tex]4y = 8[/tex]

4) Divide both sides by 4.

[tex]y = \frac{8}{4} [/tex]

4) Simplify 8/4 to 2.

[tex]y = 2[/tex]

Hence, the answer is y = 2.

Calculate the breadth if the perimeter is 16cm and the length is 5cm​

Answers

Step-by-step explanation:

Given,

perimeter - 16cm

length - 5cm

find breadth,

perimeter of rectangle = l × b

16cm = 5 × b

b = 16/5

b = 3.2 cm

Step-by-step explanation:

Given

perimeter (P) = 16 cm

Length(L) = 5 cm

breadth (b) = ?

We know

P = 2 (L + b)

16 = 2 ( 5 + b)

16 = 10 + 2b

2b = 16 - 10

2b = 6

b = 6 / 2

b = 3 cm
