how are decimals added and subtracted?

Answer:

The 1st problem it is the Last Graph

The 2nd problem it is the First Graph

Answer:

Draw a rectangle.. write 13 on the two longer sides of the rectangle then write 7 on the other two shorter ones. Then add them all up and there you go your answer!

Our equation would be 13 +  13 + 7 + 7 = 40 inches

Step-by-step explanation:

The values of r for which the shaded region will be greater than or equal to 12 square units is;

r ≥ 8

We can see a rectangle and a triangle in the given image.

With the triangle being the unshaded portion of the rectangle.

Thus;

Area of shaded portion = Area of rectangle - area of rectangle.

We know that formula for area of rectangle is;

A_r = length × width

Thus; A_r = 3 × r

A_r = 3r

Area of a triangle is;

A_t = ½ × base × height

A_t = ½ × r × 3

A_t = ½(3r)

Thus;

Area of shaded portion = 3r - ½(3r)

Area of unshaded portion = 1.5r

We are told that the area of the unshaded region should be greater than or equal to 12. Thus;

1.5r ≥ 12

r ≥ 12/1.5

r ≥ 8

            Addition and Multiplication.

            Addition and Multiplication.

            Additional and Multiplication.

Step-by-step explanation:

Communitive Property:

Addition; When two numbers are added, the sum is the same regardless of the order in which the  numbers are added. (3 + 2 = 5 or 2 + 3 = 5)

Multiplication; When two numbers are multiplied together, the product is the same regardless of the order in which the numbers are multiplied.

(4 x 3 = 12 or 3 x 4 = 12)

Associative Property:

Addition; When three or more numbers are added, the sum is the same regardless of the way in  which the numbers are grouped.

6 + (4 + 3) = 13 or (6 + 4) + 3 = 13

Multiplication; When three or more numbers are multiplied, the product is the same regardless of

the way in which the numbers are grouped.

6 x (4 x 3) = 72 or (6 x 4) x 3 = 72

Identity Property:

Addition; The sum of any number and zero is that number.

(10 + 0 = 10)

Multiplication; The product of any number and one is that number.

(33 x 1 = 33)

Distributive Property:

The sum of two numbers times a third number is equal  to the sum of each addend times the third number. 6(3 + 4)

(Multiply 6 by both numbers, 6 x 3 = 18 and 6 x 4 = 24, and then add the sums; 18 + 24 = 48.

Answer: I think the first one is subtraction.

Step-by-step explanation:

Answer:

The purpose of the League of Nations was to try and keep peace between the other nations so another would not break out (WW2 happens 2 decades later). The idea was to prevent wars through disarmament, collective security, and negotiation. It crashed and burned because it created the Treaty of Versailles (made Germany pay reparations), aims were too ambitious, Germany and Russia and USA were not members, no army, organization was not well organized, and decisions were unanimous.

The League of Nations was an international organization, headquartered in Geneva, Switzerland, created after the First World War to provide a forum for resolving international disputes. Unfortunately, the League failed miserably in its intended goal: to prevent another world war from happening (WW2 broke out only two decades later). The idea was for the League of Nations to prevent wars through disarmament, collective security, and negotiation.

It's pretty easy just do some subtraction.

Actually look and pay attention in class this is like grade 1 math.

Answer:

1. Slope = -3.000/2.000 = -1.500

2.  x-intercept = 0/3 = 0.00000

3. y-intercept = 0/2 = 0.00000

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2*y-(-3*x)=0

Equation of a Straight Line

1.1     Solve   2y+3x  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  2y+3x  = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 0/2 so this line "cuts" the y axis at y= 0.00000

 y-intercept = 0/2  =  0.00000  

Calculate the X-Intercept :

When y = 0 the value of x is 0/3 Our line therefore "cuts" the x axis at x= 0.00000

 x-intercept = 0/3  =  0.00000  

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -0.000 and for x=2.000, the value of y is -3.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -3.000 - -0.000 = -3.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = -3.000/2.000 = -1.500  

Geometric figure: Straight Line

 Slope = -3.000/2.000 = -1.500

 x-intercept = 0/3 = 0.00000

 y-intercept = 0/2 = 0.00000
