write each expression without using the absolute value symbol |14-(x-6)|
THIS IS 15 POINTS PLSSSSSSSSSSSSSS HELP

Answers

To start, we need to recognize that absolute value is a way of expressing the magnitude of a number, regardless of its sign. Thus, to get rid of the absolute value, we need to consider the two cases in which the expression can have either a positive or a negative sign.

For the case of a positive sign, we can simply write the expression as: 14-(x-6)

For the case of a negative sign, we can multiply both sides of the equation by -1 to get: -14 + (x-6)

Overall, we can express the expression without the absolute value symbol as:

14-(x-6) or -14 + (x-6)

We need the whole equation

A hat that costs $8 is sold to the customer for $12.
A pair of shoes that costs $20 is sold to the customer for $35.
A shirt that costs $12 is sold to the customer for $20

Answers

Answer: A pair of shoes that costs $20 is sold to the customer for $35, and A shirt that costs $12 is sold to the customer for $20.

Step-by-step explanation:

1. Half (or 50%) of 20 is 10, so 20+10=30, but 35 is bigger than 30.

2. Half (or 50%) of 12 is 6, so 12+8=18, but 20 is bigger than 18.

3(y-2x) = 9
x - 4 = 0


PLSSS HELPPP

Answers

Answer:

(x, y) = (4, 11).

Step-by-step explanation:

We have two equations:

3(y-2x) = 9

x - 4 = 0

From equation 2, we have x = 4. We can substitute this value into equation 1 and solve for y:

3(y-2x) = 9

3(y-2(4)) = 9 (substitute x = 4)

3(y-8) = 9

3y - 24 = 9

3y = 33

y = 11

Therefore, the solution to the system of equations is (x, y) = (4, 11).

Answers

Answer:

B

Step-by-step explanation: The box represents the middle 50% of the data, with the bottom and top of the box representing the first and third quartiles, respectively. The line inside the box represents the median.

The whiskers extend from the box to show the range of the data, excluding outliers. Outliers are typically shown as individual points outside the whiskers.

Based on this information, we can see that the box in the box plot represents the middle 50% of the data. Therefore, the answer is B. The box, from 44 to 52, includes about 50% of the data.

Answer:

A = 324m²

Step-by-step explanation:

Formula for finding the surface area of a rectangular prism:

2(wl + hl + hw)

First, let's find out which one of the measurements is the height, length, or width.

6m = length

16m = width

3m = height

Next, we calculate the surface area. We have to do the formula one by one too.

2(wl + hl + hw)

2(16x6 + 3x6 + 3x16)

16 x 6 = 96

3 x 6 = 18

3 x 16 = 48

Now, we add those together.

96 + 18 + 48 = 162

Lastly, multiply by 2.

162 x 2 = 324

Therefore, A = 324m²

Polygon JKLM is drawn with vertices J(−4, −3), K(−4, −6), L(−1, −6), M(−1, −3). Determine the image coordinates of L′ if the pre-image is reflected across y = −3.

L′(−3, 6)
L′(−1, 6)
L′(−1, 0)
L′(1, 0)

Answers

To reflect the pre-image across y = -3, we need to flip the entire polygon over the line y = -3. This means that the x-coordinates of each point will remain the same, but the y-coordinates will be reflected across the line.The y-coordinate of point L is -6, which is 3 units below the line y = -3. When reflected, this point will be 3 units above the line y = -3. Therefore, the image coordinates of L' will be (−1, 0), since the x-coordinate of L is -1 and the y-coordinate of L' is 3 units above y = -3, which is 0.So, the image coordinates of L' are (−1, 0).

Use diagrams or the description of equivalent ratios to show that the ratios 2:3, 4:6, and 8:12 are equivalent ratios.

Answers

They are equivalent because 2:3, 2 × 2 = 4, 3 × 2 = 6 which makes up 4:6, 2 × 4 = 8, 2 × 6 = 12 which makes it 8:12. which makes it 2.

Yes, All the ratio 2 : 3, 4 : 6 and 8 : 12 are equal.

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.

Given that;

All the ratios are,

⇒ 2 : 3, 4 : 6 and 8 : 12

Now,

Since, All the ratios are,

⇒ 2 : 3, 4 : 6 and 8 : 12

Hence, Simplify the ratio as;

⇒ 2 : 3 = 2/3

⇒ 4 : 6 = 4 / 6

           = 2 / 3

           = 2 : 3

⇒ 8 : 12 = 8 / 12

             = 4 / 6

             = 2 / 3

             = 2 : 3

Thus, All the ratio are equal.

2002 - 84 years = 1918

________________________________________________

This follows the same principal as you subtracting your age from the current year to find the year in which you were born.

Answer:

Celebration of 84 birthday = 2002

Year in which she was born = 2002 - 84

                                               =1918

Therefore Great-Grandma was born on the year 1918
