Answer:

x = 12

Step-by-step explanation:

15 + x = 27

subtract 15 from each side of the equation:

15 - 15 + x = 27 - 15

x = 12

Answer:

(a) Expanded form:

[tex]((X_1 + X_1Y_1) - X_1Z_1) + ((X_2 + X_2Y_2) - X_2Z_2) + ((X_3 + X_3Y_3) - X_3Z_3) + ((X_4 + X_4Y_4) - X_4Z_4)[/tex]

(b) The value of the expression: -21

Step-by-step explanation:

Given

[tex]\sum \limit^4_{i=1}\ ((X_i+X_iY_i) - X_iZ_i)[/tex]

Solving (a): The expanded form:

This means that we substitute the values of i from 1 to 4 in the above expression.

So, the expression becomes:

[tex]((X_1 + X_1Y_1) - X_1Z_1) + ((X_2 + X_2Y_2) - X_2Z_2) + ((X_3 + X_3Y_3) - X_3Z_3) + ((X_4 + X_4Y_4) - X_4Z_4)[/tex]

Solving (b): The value of the expression

To do this, we simply substitute the given values of X1, X2....... in the expression.

This gives:

So, the expression becomes:

[tex]((0 + 0*5) - 0*0) + ((1 + 1*26) - 1*-2) + ((12 + 12*-2) - 12*3) + ((-1 + -1*25) - -1*24)[/tex]

Simplify each bracket

[tex]((0 + 0) - 0) + ((1 + 26) +2) + ((12 -24) - 36) + ((-1 -25) +24)[/tex]

[tex]0 + 29 -48 -2[/tex]

[tex]-21[/tex]

Hence, the result of the expression is -21

Answer:  Shawn payed the cashier $15.25

Step-by-step explanation:

Answer:

Width of the rectangle = 6.325 units

Length of the rectangle = 12.65 units

Side length of the square the 6.325 units.

Step-by-step explanation:

The length of a rectangle is twice the width. The area of the rectangle is 80 square units.

The area of the rectangle = Length × Width

Length = 2W

80 square units = 2W × W

80 = 2W²

W² = 80/2

W² = 40

W = √40

Width of the rectangle = 6.3245553203 units

Approximately = 6.325 units

Length = 2 × Width

= 2 × 6.325

= 12.65 units

• Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each​ square?

We you divide a rectangle into 2 squares,

The length is divided into two.

Hence, the length of the rectangle = 12.65 units

12.65 units ÷ 2 = 6.325 units.

Hence, the side length of the square the 6.325 units.

The length and width of the rectangle are 13.26 units and 6.63 units if the length of a rectangle is twice the width.

It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

It is given that:

The length of a rectangle is twice the width. The area of rectangle 88 is square units.

As we know:

The area of the rectangle = Length×Width

L = 2W

88  = 2W × W

88 = 2W²

W² = 44

W = √44 = 6.63 units

L = 2 × Width

= 2×6.63

= 13.26 units

Thus, the length and width of the rectangle are 13.26 units and 6.63 units if the length of a rectangle is twice the width.

Answer:

Step-by-step explanation:

Answer:

Percent Increase

Step-by-step explanation:

Percent Increase because if the necklace was bought for $260, and was marked up by 30%, it means it was originally a lower price, that was multiplied by 130%.

Explanation by algebra:

x + 0.30x = 260

1.3x = 260

x = 260/1.3

x = 200

The necklace was originally $200, and it was marked up by 30$, making it $260.

Answer:

3x + 2y = 11

3x + y = 11 - 2

3x + y = 9

x + y = 9/3

x + y = 3

x = 3 - y

5x - y = 14

x - y = 14/5

x - y = 2.8

x = 2.8 + y

14Answer:

3

Step-by-step explanation:

solve for y in first equation

5x-y=14

-y=14-5x

y=5x-14

substitute y value (5x-14) into 2nd equation

3x+2 (5x-14)=11

3x+10x-28=11

13x=39

Answer:

3. X = (-4, -5), Y = (0, -3), Z = (-1, -7)

4. Refer back to my explanation.

5. a. Refer back to my explanation.

5. b. 28 units^2; please solve for the other rectangle.

5. c. No, because translation means moving the figure, not changing the shape or size.

Step-by-step explanation:

Warning in advance: the picture is very blurry when looking at the numbers on the graph so I have tried my best to decipher them.

3.

First, write down the ordered pairs for X, Y, and Z.

X = (-1, 4)

Y = (3, 6)

Z = (2, 2)

Note that horizontal movement (moving left or right) affects only the x coordinate. If you are moving to the left, you will subtract from the x coordinate. If you are moving to the right, you will add to the x coordinate.

Vertical movement (moving up or down) affects only the y coordinate. If you are moving up, you will add to the y coordinate. If you are moving down, you will subtract from the y coordinate.

Apply this concept to the ordered pairs:

Moving left = subtraction from x coordinate

Moving down = subtraction from y coordinate

X2 = (-1 - 3, 4 - 9) = (-4, -5)

Y2 = (3 - 3, 6 - 9) = (0, -3)

Z2 = (2 - 3, 2 - 9) = (-1, -7)

Your new image should have X at (-4, -5), Y at (0, -3), and Z at (-1, -7).

4.

After reading the concepts and seeing my explanation and demonstration, please try number 4 on your own. If you have any questions, feel free to ask me for help.

5. a.

The same goes for this problem since it is the same concept.

5. b.

To find the area of a rectangle, use the equation length × width, also known as l × w. In order to figure out what the length and width are equal to, count the units on the graph. JK is 7 units wide. Since this is a rectangle, ML will be the same width, 7 units. KL is 4 units long so JM will also be 4 units long. Now that we know the number of units, we can plug the numbers into the formula:

4 units × 7 units = 28 units^2

The question asks to solve for the area of each rectangle so please try the same for the rectangle you create from problem 5. a.

5. c.

The area of a figure will not change after translation because translation does not affect the figure's size or shape. If the figure is only moved, then no part of its area is changed so no, the area of a figure will not change.

Answer:5/6=25/blank

Step-by-step explanation:so 5/6 the top is times five forget the bottom for now just think of 5 and 25

[5x5] equals 25 so you already got the top

now for the bottom since you multiply the top by five you have to do that to the bottom so that will be    [6x5] that equals 30 so you got your answer

  y = 4√10

  z = 12√10

Step-by-step explanation:

The geometric mean rules apply. Each of the segments labeled with a letter is the geometric mean of the segments it touches on the hypotenuse.

  x = √(4×36) = 12

  y = √(4×(4+36)) = 4√10

  z = √(36×(36+4)) = 12√10

Convert 0.8km to hours and minutes

One of the condition for a successful conversion is that: only units of the same metric can be converted.

i.e.

Meters can be converted to feet (they both measure distance)

Days can be converted to years (they both measure time)

Pounds can be converted to grams (they both measure weight)

But in the given question, you attempt to convert from distance to time.

This is not possible, because time and distance are different measurements

Answer:

y = 5

Step-by-step explanation:

40 = 8y

divide both sides by 8, isolating y by itself:

40/8 = 8y/8

5 = y

rearrange the equation so the y is on the left side

y = 5

The answer is y = 5

We can check by plugging in y = 5 into the original equation:

40 = 8y

40 = 8(5)

40 = 40

correct
