Answer:

x= -1.22

Step-by-step explanation:

I think in this case you would be solving for x. So, to start you would expand the 2 out to the (x-3). That would give you 2x-6. Then you would expand the 7 out to the (x+2). That would give you 7x+14. You would then be left with       2x-3+7x+14. You would then combine like terms and get 9x+11. To solve for x you would subtract 11 leaving you with 9x= -11. From there you would divide -11 by 9 and get x= -1.22.

Have a wonderful day!! :)

Order of operations: Parentheses, Exponents, Multiplication, Division, Addition/Subtraction

We'll start with division first. 10/2 = 5, 3/3 = 1

Then, we'll add the terms left. 5 + 3 + 6 + 1 = 15

Answer:

Step-by-step explanation:

You know the general term of an AP is ...

  an = a1 +d(n-1)

Here, a1 = k. The common difference is ...

  2k/3 -k = -k/3

So, the general term is ...

  an = k +(k/3)(n -1) . . . . the general term

__

The 6th term is then ...

  a6 = k + (k/3)(6 -1) = (3k +5k)/3 = 8k/3 . . . . 6th term

__

The 20th term is ...

  a20 = k + (k/3)(20 -1) = 22k/3

If this is 15, then the value of k is ...

  22k/3 = 15

  22k = 45

  k = 45/22 . . . . value of k for a20 = 15

D.  If you take a very large sample of the times Jackson tunes in to his favorite TV station, a commercial will be on about 35% of the time.

This is the right answer

Edge 2020

If you take a very large sample of the times Jackson tunes in to his favorite TV station, a commercial will be on  about [tex]35\%[/tex] of the time.

Probability refers to the branch of mathematics regarding numerical descriptions of how likely an event is to occur. The probability of an event is a number between [tex]\boldsymbol{0}[/tex] and [tex]\boldsymbol{1}[/tex]

[tex]0[/tex] indicates impossibility of the event and [tex]1[/tex] indicates certainty.

If Jackson turns on his favorite TV station at a randomly selected time, the probability that the current show will be on is that ''If you take a very large sample of the times Jackson tunes in to his favorite TV station, a commercial will be on  about [tex]35\%[/tex] of the time.''

Answer:

x =  2√13.

Step-by-step explanation:

Using the Pythagoras theorem:

14^2 = x^2 + 12^2

x^2 = 14^2 - 12^2

x^2 = (14 + 12)(14 - 12) = 52

x = √52

x = √4*√13

x = 2√13.

Answer:

c.)2 g/ml

Step-by-step explanation:

Given:

Mass of block = 12 g

Volume of block = 6 ml

Required:

Density of the block

SOLUTION:

Density is given as the mass of the block per unit volume.

Thus, density = mass/volume

Density of block = [tex] \frac{12 g}{6 ml} [/tex]

= 2 g/ml.

The answer is c. 2 g/ml.

Answer:

y = 40°

Step-by-step explanation:

Hi !

2y + (y + 10) + 50° = 180°

3y = 180° - 50° - 10°

3y = 120°

y = 120° ÷ 3

y = 40°

Answer: y =5(5)-3

5*5=25-3 =22  ANSWER IS y=22

Answer:

x=0.2, y=6

Step-by-step explanation:

Since y=20x+2, 5x+y=7 => 5x + (20x +2 ) = 7

                                                     25x + 2 = 7

                                                           25x = 5

                                                                x = 0.2

so y = 20x + 2 = 20* 0.2 +2 = 4 + 2 = 6

so the final solution is [tex]\left \{ {{y=6} \atop {x=0.2}} \right.[/tex]

The values of x and y for the given simultaneous equation are;

x = 0.2 and y = 6

We are given 2 simultaneous equations;

5x + y = 7   ---(eq 1)

20x + 2 = y   ----(eq 2)

Put 20x + 2 for y in eq 1;

5x + 20x + 2 = 7

25x + 2 = 7

25x = 7 - 2

25x = 5

x = 5/25

x = 0.2

Put 0.2 for x in eq 2 to get;

20(0.2) + 2 = y

4 + 2 = y

y = 6

In conclusion, the values of x and y are x = 0.2 and y = 6.
