How to find perimeter with equations

I attached a pic of the problem I’m really struggling with, if I could get a step by step explanation of how to do it that would be great. Thanks so much

Answers

Step-by-step explanation:

In blue colour square

Perimeter= 4 × side

= 4 (3x +7)

=12x +28 unit

In green colour square

Perimeter= 4 × side

= 4 ( 5x+1)

= 20x +4 unit

Answer:

12x + 28 = p

20x + 4 = p

Step-by-step explanation:

Assuming that both shapes are square, the perimeter of a square is the equation:

4 * x = p

Where x is the length of one side. Plug the variables in for the first square:

4 * (3x + 7) = p

Expand the brackets:

4 * 3x = 12x

4 * 7 = 28

12x + 28 = p

For the second square, plug the variables in again:

4 * (5x + 1) = p

Expand the brackets:

4 * 5x = 20x

4 * 1 = 4

20x + 4 = p

Hope this helps!

10,50,81,20

Answers

Answer:

81

Step-by-step explanation:

At the start of his work day, Mr. Eriksen had 20 boxes of light bulbs tested and ready to be shipped. On average, he can test 40 boxes of light bulbs each hour. Of the 40 boxes tested each hour, he sets aside 5 boxes for retesting. The remaining boxes are marked as ready to be shipped.

A: Mr. Eriksen's situation can be represented by a linear function. Identify the rate of change and initial value of this function. Explain what these values represent in terms of the situation.

B: Write an equation in slope-intercept form to represent the situation. Use x for the independent variable and y for the dependent variable. Identify what both variables represent.

Answers

Answer:

See below

Step-by-step explanation:

Initial value is 20 as there are already 20 boxes ready for shipment.

Each hour 40 - 5 = 35 boxes are ready for shipment

The linear function for this case is:

y = 35x + 20

35 is the slope or rate of change, 20 is the y-intercept.

y- the number of boxes ready for shipment after x hours.

Use the Distributive Property to write an equivalent expression for 21x+7

Answers

Answer: 7(3x+1)

Step-by-step explanation:

there is a common factor of 7 in both 21 and 7. therefore you can take a 7 out of the equation to get 7(3x+1)

extra: 7 times 3x = 21x and 7 times 1 = 7. this is how you verify your answer is correct.

Step-by-step explanation:

4 lbs 7 oz; oz
conversions ratios thing

Answers

Answer:

4 lb 7 oz = 71 oz

Step-by-step explanation:

Do you need to convert 4 lb 7 oz into oz?

If so, do the following.

Obviously, 7 oz is already in oz, so all you need to do is convert 4 lb into oz and then add 7 oz.

1 lb = 16 oz

For every lb, there are 16 oz. To convert lb to oz, multiply the number of lb by 16.

4 lb = 4 * 16 oz = 64 oz

4 lb 7 oz = 4 lb + 7 oz = 64 oz + 7 oz = 71 oz

Last night 30cm of snow fell in 6 hours. If it continues snowing at the
same rate, how long will it take for 45cm of snow to fall?​

Answers

Answer: 9 hrs for 45cm of snow to fall

Step-by-step

If 30cm = 6 hrs

Then divide 30/6 to get the unit rate of the amount of snow per hr

Which is 5/1

So 5cm per hr

Then add 30+5+5+5 to get 45

And since we know 5cm equal 1 hr

Add the original amount of hours which is 6 plus 3 ones

Which is 6+1+1+1

In total, it will take 9 hrs for 45cm of snow to fall.

How to solve linear equation

Answers

You can use elimination and substitution method

EXAMPLE :

Given :

2x + y = 5

3x - 5y = 1

2x + y = 5 (× -5)

3x - 5y = 1

__________

-10x - 5y = - 25

3x - 5y = 1

____________ _ (elimination)

-13x = - 26

x = - 26/-13

x = 2

Substitution x = 2 to 2x + y = 5 :

2x + y = 5

2(2) + y = 5

4 + y = 5

y = 5 - 4

y = 1

13- (x + 6) = 4x - 3

Answers

Step-by-step explanation:

13 - (x + 6) = 4x - 3

13 -x -6 = 4x - 3

Group like terms

13 - 6 + 3 = 4x + x

13 - 3 = 5x

10 = 5x

Divide both sides by 5

10/5 = 5x/5

2 = x

Therefore, x is equal to 2.

Using proportions, it is found that each out is [tex]\frac{1}{54}[/tex] of all the outs in a 9-inning baseball game.

Supposing a 9-inning baseball game, each team has the right to 27 outs.

Two teams, thus, there are [tex]2 \times 27 = 54[/tex] outs.

This means that each out in a game [tex]\frac{1}{54}[/tex] of all the outs in a 9-inning baseball game.
