Step-by-step explanation:

Rose age = 3(x-6) = 15

Rose's brothers age = x

3(x-6) = 15

3x - 18 = 15

3x = 15+18

x = 33/3 =11

Rose's brothers age = x =11

I hope im rght!!i

Answer:

11 years old

Step-by-step explanation:

Create an equation where x is her brother's age

15 = 3(x - 6)

Solve for x:

15 = 3x - 18

33 = 3x

11 = x

So, her brother is 11 years old

Answer:

-16.22

Step-by-step explanation:

You take both numbers and subtract normally because adding a negative number and a positive number is the same as subtracting them without the signs so you do 22.45-6.23 and you get 16.22 and then you just put the negative sign in front and you get 16.22.

Answer: The equation used to find the value of x is 5x - 4 = 3x + 10. The value of x is determined to be 7.

Step-by-step explanation:

Four less than the product of a number (x) and 5 = 5x - 4

8 more than 2 added to 3 times the number = 3x + 2 + 8 = 3x + 10

Four less than the product of a number (x) and 5 is equal to 8 more than 2 added to 3 times the number => 5x - 4 = 3x + 10

                                                         5x - 3x = 10 + 4

                                                         2x = 14

                                                         x = 14/2

                 therefore,                      x = 7

Answer:

y = 8x + 38

Step-by-step explanation:

parallel to y=8x -3, that means the slope(m) = 8

points : -4 , 6

now put them in the formula y = mx + b

6 = 8(-4) + b

6 = -32 + b

6 + 32 = b

b = 38

y = 8x + 38

Answer:

$42.00

Step-by-step explanation:

We can represent the given information as a ratio:

% of original price : price

                          5% : $2.00

Then, we can multiply both sides of this ratio by 20 (or 100% / 5%) to get 100% of the original price, which IS the original price.

5%      :  $2.00

↓ × 20   ↓ × 20

100%  :  $40.00

Now that we know the original price, we can add $2.00 to get the new price.

$40.00 + $2.00 = $42.00

Answer:

Step-by-step explanation:

Scale factor of JKLM to EFGH is 5/2.

Value of x = 27.5

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size.

Given,

JKLM ~ EFGH

Scale factor = JK/EF = 20/8 = 5/2

So, KL/GF  = 5/2

x/11 = 5/2

x = 55/2

x = 27.5

There is scale factor of 5/2 from JKLM to EFGH.

27.5 is value of x.

Answer:

∠DBC = 155°

Step-by-step explanation:

Assuming that ABC is a straight line.

Angles on a straight line sum to 180°.

⇒ (2x² + 3x - 2) + ∠DBC = 180°

⇒ ∠DBC = 180° - (2x² + 3x - 2)

The sum of the interior angles of a triangle is 180°:

⇒ (x² + 1) + (4x + 3) + ∠DBC = 180°

⇒ ∠DBC = 180° - (x² + 1) - (4x + 3)

Therefore, we can equate the equations and solve for x:

⇒ ∠DBC = ∠DBC

⇒ 180 - (2x² + 3x - 2) = 180 - (x² + 1) - (4x + 3)

⇒ 180 - 180 = (2x² + 3x - 2) - (x² + 1) - (4x + 3)

⇒ (2x² + 3x - 2) - (x² + 1) - (4x + 3) = 0

⇒ 2x² + 3x - 2 - x² - 1 - 4x - 3 = 0

⇒ x² - x - 6 = 0

⇒ x² + 2x - 3x - 6 = 0

⇒ x(x + 2) - 3(x + 2) = 0

⇒ (x + 2)(x - 3) = 0

Therefore,  x = -2, x = 3

As angles are positive, x = 3 only

Substituting found value of x into the angle expressions:

⇒ ∠BDC = x² + 1 = (3)² + 1 = 10°

⇒ ∠DCB = 4x + 3 = 4(3) + 3 = 15°

The sum of the interior angles of a triangle is 180°:

⇒ ∠DBC  + ∠BDC + ∠DCB = 180°

⇒ ∠DBC = 180° - ∠BDC - ∠DCB

⇒ ∠DBC = 180° - 10° - 15°

⇒ ∠DBC = 155°

Now

<DBC=180-25=155°

Answer:

x=12°

Step-by-step explanation:

as the measures of angles of triangle = 180°

then: 180=48+30+x

then x= 180-(48+30)= 102°

Answer:

22.5°

Step-by-step explanation:

We know that the measure of straight line is 180° . Therefore the sum of all angles will be 180° .

⇒ 90° + x + 3x = 180°

⇒ 90° + 4x = 180°

⇒ 4x = 90°

⇒ x = 90°/4

⇒ x = 22.5°

An order-preserving function is a function that preserves the order of its inputs. In other words, if x is less than y, then f(x) will be less than f(y).

The statement "f is order-preserving if x < y implies f(x) < f(y)" means that if x is less than y, then f(x) must be less than f(y). This is a necessary condition for a function to be order-preserving. However, it is not a sufficient condition. For example, the function f(x) = x^2 is not order-preserving, because 2 < 3, but f(2) = 4 > f(3) = 9.

In summary, order-preserving functions are useful in situations where we need to preserve the order of a set of data.

The measure of each exterior angle in a polygon is equal to (360/n) degrees, where n is the number of sides.

To find the measure of each individual exterior angle in any polygon, you will need to know the number of sides, which is represented by 'n'. The formula to calculate the measure of each exterior angle is: (360/n) degrees. This formula can be used no matter how many sides the polygon has. For example, if you have a pentagon, which has 5 sides, the measure of each exterior angle is (360/5) degrees, or 72 degrees. If you have a hexagon, which has 6 sides, the measure of each exterior angle is (360/6) degrees, or 60 degrees. This formula can be used for any polygon, regardless of the number of sides.

The variance of Billy's grades obtained from his test scores is 15.76

The variance is a measure of variability or spread a dataset. The variance can be calculated from the sum of the square of the differences of the data points from the mean divided by the number or count of the data points.

The variance of Billy's test scores can be calculated by finding the mean or the average of the scores, then finding the sum of the squares of the differences of each score from the mean as follows;

The mean score = (89 + 88 + 93 + 90 + 81)/5 = 88.2

The square of the differences of the values from the mean can be calculated as follows;

(89 - 88.2)² = 0.64, (88 - 88.2)² = 0.04, (93 - 88.2)² = 23.04, (90 - 88.2)² = 3.24, and (81 - 88.2)² = 51.84

The sum of the square of the differences is therefore;

0.64 + 0.04 + 23.04 + 3.24 + 51.84 = 78.8
