Help! problem:5-x=11+x

1 answer:

7 0

The answer is x=-3

5-x=11+x
-11 -11 First subtract 11
-6-x=x
+x +x Now add x to both sides
-6=2x
~2 ~2 Finally divide by 2
-3=x Your answer is x=-3

Amanda's sewing a flag for a competition. The dimensions of her flag are shown below. Approximately, how many square yards of bl

DedPeter [7]

To calculate the area of the black material on the flag, we need the shape and the dimensions of the black material itself.

Since the question is incomplete, as the dimension of the flag and the dimension of the black material are not given, I will provide a general explanation

Assume the shape of the black material is a rectangle.

The area will be calculated as:

$Area = Length * Width$

Take for instance;

$Length = 4yd;\ Width = 5yd$

The area is:

$Area = 4yd * 5yd$

$Area = 20yd^2$

Assume the shape of the black material is a square.

The area will be calculated as:

$Area =Length^2$

Take for instance;

$Length = 4yd$

The area is:

$Area = (4yd)^2$

$Area = 16yd^2$

Assume the shape of the black material is a triangle

The area will be calculated as:

$Area = 0.5 * Base * Height$

Take for instance;

$Base = 4yd;\ Height = 5yd$

The area is:

$Area = 0.5 * 4yd * 5yd$

$Area =10yd^2$

So, in general.

You need to first get the shape of the black segment on the flag, then calculate the area using the appropriate formula.

On a coordinate plane, what is the distance between the points (-1,5) and (2,5)? Enter the answer in the box.

zlopas [31]

Answer:

The distance between (-1,5) and (2,5) is √9 or 3.

Step-by-step explanation:

Okay first, just for explaining purposes, let's call the ordered pair (-1,5) letter A and ordered pair (2,5) letter B.

Now to the answer. To start you use the distance formula. which is:

d=√( (x2-x1)²+(y2-y1)²)

Then you solve by plugging the ordered pairs into the formula where -1 from point A is X1 and 5 from point A is Y1. 2 from point B is X2 and 5 from point B is Y2.

When you solve it should look like this:

1. d=√( (x2-x1)²+(y2-y1)²)

2. d=√( (2- -1)²+(5-5)²) *2 minus a negative one means plus so we get 3*

3. d=√( (3)²+(0)²)

4. d=√( 9+0)

5. √9 = 3
