Answer:

(4, -3 )

General Formulas and Concepts:

<u>Pre-Algebra I</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

  • Midpoint Formula: (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} )

Step-by-step explanation:

<u>Step 1: Define</u>

R (9, 3)

S (-1, -9)

<u>Step 2: Find midpoint</u>

  1. Substitute:                    (\frac{9-1}{2}, \frac{3-9}{2} )
  2. Subtract:                       (\frac{8}{2}, \frac{-6}{2} )
  3. Divide:                          (4, -3 )

The perimeter of a playing card is 30 centimeters. The area is 50 square centimeters. What are the dimensions of the playing car
Arlecino [84]

Step-by-step explanation:

We get two equations here. One for the area and one for the perimeter. The area gives us x×y=50. The perimeter, if we have a rectangle, x+y+x+y=30=2x+2y. For this to work we need to make a simple expression for x or y. Let's go with x here. 2x+2y=30 so x=15-y. if we fill that in the other equation we get (15-y)×y=50 (see picture). y=5 or y=10. If we fill in x×5=50 we get x=10 and vice versa. So the dimensions are 5 centimeters by 10 centimeters

You start a search for a buried object by marking the center of a field as (0, 0), with coordinates giving distances in yards. C
pychu [463]

The coordinates to the second spot can be represented by the coordinates

(-12 + 3, 8 -11)

Since we are going 3 yards to the east we would be affecting the x-axis and since we are going east we will need to add 3 yards the x axis of the first spot


11 yards south would be affecting the y- axis negatively. We would need to subtract 11 from the y- axis of the first spot.

the coordinates of the second spot would be

-12 +3 = -9

8 -11 = -3


(-9, -3)

What is 20×40+3×9÷3+4
-Dominant- [34]
<span><span /><span>The answer to that problem is 813. When you are given a problem like this, you can answer it by using the MDAS technique. MDAS stands for multiplication, division, addition, and subtraction. Since you are following the MDAS technique, you are asked to answer the equation based on MDAS order. To put this simply, look at the example below:

     20x40+3x9/3+4
     800+3x9/3+4
     800+27/3+4
     800+9+4
     809+4
     813</span></span>  

You can clearly see the MDAS order by following the bold text.
