The other number given the average of the two numbers and one of the numbers is 10x - 3.

The average of a set of numbers is the mean of the numbers. The average of a set of numbers is determined by adding the numbers together and dividing it by the sum of numbers. Average is a measure of central tendency.

In order to determine the second answer, subtract the first number from the sum of numbers.

Average = sum of numbers / total numbers

5x = sum of numbers / 2

Sum of the two numbers = 5x  × 2

Sum of the two numbers = 10x

If one of the numbers is 3, the other number is: 10x - 3

The estimate closest to an average​ person's weight is 80​kg

The weights are given as:

8 kg, 80 kg and 800 kg

To answer this question, I will assume that a person means an adult

An adult that weighs 8 kg is very much under weight

Because the average weight of a person is around 60 to 90 kg

The products of the matrices are

        [-4     19]

ST =  [8   -21]      

and

        [-12      -8]

TS = [-25      -10]

The matrices are given as

      [4      1]

S =  [-3   -2]

      [0      4]

T =  [-4   3]

The product of the matrices is then calculated as

        [4 * 0 + 1 * -4      4 * 4 + 1 * 3]      

ST =  [-3 * 0 - 2 * -4   -3 * 4 - 3 * 3]      

Evaluate the sum or difference of products

So, we have

        [-4     19]

ST =  [8   -21]      

Also, we have

        [0 * 4 + 4 * -3      0 * 1 + 4 * -2]      

TS = [-4 * 4 + 3 * -3      -4 * 1 + 3 * -2]      

Evaluate the sum or difference of products

So, we have

        [-12      -8]

TS = [-25      -10]

Hence, the products of the matrices are

        [-4     19]

ST =  [8   -21]      

and

The required step of indirect proving is to assume AABC is an acute triangle. Option B is correct.

Given that,
AABC is not an acute triangle.

What is the first step of indirectly proving this statement is to be determined.

The angle can be defined as the one line inclined over another line.

Here,
Indirect proving implies proving with contradictions,
So in order to prove AABC is not an acute triangle, we have first assumed that AABC is an acute triangle.

Thus, the required step of indirect proving is to assume AABC is an acute triangle. Option B is correct.

By using the Pythagorean theorem, we conclude that the length of the segment is 3.2 units.

We want to find the length of the graphed segment. In the grid, we can see that the horizontal displacement between the two ends measures one unit, and the vertical displacement measures 3 units.

So the length can be tought as the hypotenuse of a right triangle whose legs measure one unit and 3 units.

By using the Pythagorean theorem, we can find that lenght L by.

L^2 = 1^2 + 3^2

Now, if we apply the square root in both sides we will get:

L = √(1^2 + 3^2) = √(1 + 9) = √10 = 3.2

We conclude that the length of the segment is 3.2 units.

The statement that there is $2.875 increase for each increase in unit of rose in the bouquet is true that tells about the relationship of price to number of roses per bouquet.

Given that a 12-rose bouquet costs $42, and a 20-rose bouquet costs$65.

We are required to make a  statement about the relationship of price to number of roses per bouquet which is true.

If we observe each value then the coordinates will be (12,42) and (20,65).

Slope=(65-42/20-12)

=23/8

=2.875

Hence the statement that there is $2.875 increase for each increase in unit of rose in the bouquet is true that tells about the relationship of price to number of roses per bouquet.

Step-by-step explanation:

Answer:

y=2x+6

Step-by-step explanation:

First find the gradient of the perpendicular line. We can do this by turing the given gradient into a negative reciprocal.

-1/2 -> 2 (new gradient)

substitute new gradient into y=mx+c as well as the values for x and y from the given coordinate (-2,2)

y=mx+c

2=2(-2)+c

then solve for c

2=-4+c

c=6

therefore the formula for the line is y=2x+6

Answer: 30

Step-by-step explanation:

Think of each number in the ratio of 2:5 as a group. Each group has to be the same. 2 groups of boys : 5 groups of girls. There are 12 boys on the bus. So the 12 boys are split into 2 groups. 12/2=6. 6 boys are in each group. Since we now know that each group had 6 kids we just need to find the number of girls. There are 5 groups of 6 girls. 5x6=30. There are 30 girls on the bus.

Answer:

?=8

Step-by-step explanation:

I substituted the ? for x

-3=x-11

first we want to isolate the x to do that, you have to find a way to move -11 to the other side. Well, x+0=x right? So all we have to do is find a way to go from -11 to 0! In this case you add 11 to both sides. This is very important so don't forget.

-3=x-11

+11    +11

-3+11=8

x=8

If you check your work, this should also go back in perfectly.

-3=8-11

or

-3=-11+8
