Answer:

23

Step-by-step explanation:

Two numbers have an average of 17, with one of the numbers being 11.

Note that to solve average, you must:

1) Add all numbers

2) Divide by the amount of numbers there is

3) Get answer.

---------------------------------------------------------------------------------------------

Note that the equation looks like:

(x + 11)/2 = 17

Note: x = the number you are solving for.

----------------------------------------------------------------------------------------------

Note the equal sign. What you do to one side, you do to the other. First, multiply 2 to both sides

(x + 11)/2(2) = 17(2)

x + 11 = 17(2)

x + 11 = 34

---------------------------------------------------------------------------------------------

Isolate the x. Subtract 11 from both sides

x + 11 (-11) = 34 (-11)

x = 34 - 11

x = 23

---------------------------------------------------------------------------------------------

23 is your answer

The average is found by adding the numbers and dividing by 2.

Since the average is 17, the total of the two numbers must equal 17 x 2 = 34.


One number is given as 11, so subtract 11 from 34:

34 - 11 = 23

The other number is 23.

Too check: add 11 and 23 and then divide by 2:

11 + 23 = 34

34/2 = 17.

worty [1.4K]

In this problem, we can imagine that all the points connect to form a triangle. The three point or vertices are located on the pitcher mount, the home plate and where the outfielder catches the ball. So in this case we are given two sides of the triangle and the angle in between the two sides.

<span>With the following conditions, we can use the cosine law to solve for the unknown 3rd side. The formula is:</span>

c^2 = a^2 + b^2 – 2 a b cos θ

Where,

a = 60.5 ft

b = 195 ft

θ = 32°

Substituting the given values:

c^2 = (60.5)^2 + (195)^2 – 2 (60.5) (195) cos 32

c^2 = 3660.25 + 38025 – 20009.7

c^2 = 21,675.56

c = 147.23 ft

<span>Therefore the outfielder throws the ball at a distance of 147.23 ft towards the home plate.</span>

Vadim26 [7]

Answer:

(7,2)

Step-by-step explanation:

x + y = 9 + 2x - 3y = 8 is really two equations, and you should show this by separating x + y = 9 from 2x - 3y = 8 through the use of a comma, or the word "and," or through writing only one equation per line.

Here you have the system of linear equations

 x +   y =  9

2x - 3y = 8.

Let's solve this system by elimination.  Mult. the 1st eqn by 3, obtaining the system

3x + 3y = 27

2x - 3y =    8

-------------------

5x = 35, so that x = 7.  Subbing 7 for x in x + y = 9, we get 7 + y = 9, indicating that y = 2.

Thus, the solution to this system of equations is (7,2).
