The perimeter of a rectangle is 40 cm. The length is 14 cm.
Let x = width of the rectangle.

Ravi says he can find the width using the equation 2(x + 14) = 40.
Fran says she can find the width using the equation 2x + 28 = 40.

Answer the questions to solve the equations and to compare the steps and solutions.

1. Which of these is the most helpful first step for solving Ravi's equation, 2(x + 14) = 40?

Circle the best answer.

Answers

Answer:

number 1 is D

number 2 is distribute 2 into x and 14(multiplying)  getting 2x+28=40

then subtract 28 from each side  40-28=12  after just simply divide 2x by its self and into 12 getting 6

number 3 is 12

number 4 is subtract 2 from both side

number 5 is divide

number 6 is 6

Kiran says that a solution to the equation `x-7=3` must also be a solution to the equation `3x-21=9`.

Write a convincing explanation as to why this is true. Explain how these are equivalent equations.

Answers

Answer: This is true because everything in the first equation was multiplied equally to get to the second equation. Every part was multiplied by three. The first equation is x-7=3 and the second can be seen as 3(x-7=3). The three will not affect x seeing that the entire equation had the same thing done to it.

a piece of wire is 28cm in length is cut into two parts, each part bend to make a square. given that area of square is 416m^2. find the perimeter of each square.

Answers

Answer:

25.488 cm and 2.512 cm

Step-by-step explanation:

Note: the area of squares is 41 cm² but not 416 m², typo

Let the sides of squares be x and y

Based on given we have equations:

4x + 4y = 28x² + y² = 41

Simplify the first equation

4x + 4y = 28x + y = 7x = 7 - y

Substitute x to solve for y:

(7 - y)² + y² = 4149 - 14y + y² + y² = 412y² - 14y + 49 - 41 = 02y² - 14y + 8 = 0y² -7y + 4 =0

Solving we get:

y= 6.372 cm or y= 0.628cm

Then

x = 0.628 cm or x = 6.372 cm

Perimeter of each square is:

4*6.372 = 25.488 cm

and

4*0.628 = 2.512 cm

Find mzC.
B
(2x – 12)
(9x – 26)
(4x + 43)

Answers

Answer:

m<C = 119°

Step-by-step explanation:

Create an equation to find the value of x.

(9x - 26)° = (2x - 12)° + (4x + 43)° (exterior angle theorem of a ∆)

Solve for x

9x - 26 = 2x - 12 + 4x + 43

Add like terms

9x - 26 = 6x + 31

9x - 6x = 26 + 31

3x = 57

Divide both sides by 3

x = 19

✔️m<C = 4x + 43

Plug in the value of x

m<C = 4(19) + 43

m<C = 76 + 43

m<C = 119°

We are performing a one-sample z-test about mean. The sample size is 64, the sample mean 56.7, the sample standard deviation is 30, and the testing mean is 60. What is the value of the test statistic?

Answers

Answer:

-0.880

Step-by-step explanation:

Mean X = 56.7

Sd = 30

N = sample size = 64

Null hypothesis:

H0:u = 60

Alternative hypothesis:

H1:u not equal to 60

This corresponds to a 2 tailed test. So we will have to use a z test with 1 mean, known population and standard deviation

Level of significance = 0.05

Z critical value = 1.96

The test statistic

Z = X - u/sd/√n

= 56.7 - 60/30√64

= -0.880

The test statistic is equal to -0.880

Consider the inequity

Step-by-step explanation:

There can be only 1 triangle formed by the given information.

What is triangle?

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon.

Given that, ABC can be formed if C=60∘, c=17√3 and a=34

Using the sine law for triangle,

A/sina = B/sinb = C/sinc

34/sina = 17√3/sin60°

⇒ sina = 90°

Since, The triangle ABC is a right triangle,

Hence, There can be only 1 triangle formed by the given information.

Michelle is planting flowers in her garden. She wants the ratio of daisies to carnations to be 3 to 2. Michelle wants to plant a total of 30 flowers. How many daisies should she plant?

Answers

She should plant 18 daisies and 12 carnations.

Steps:

Divide 30 by 5 because 3+2 is 5

The answer is 6

The proportion for daisy is 3 so multiply 3 by 6 which is 18

For carnations multiply 2 by 6

Answer:

18 Daisies and 12 Carnations

Step-by-step explanation:

The total amount of flowers adds to be 30 therefore the amount of daises plus the amount of carnations should equal 30 (d+c=30). Then your ratio of daises to carnations is 3 to 2. Which means that you are going to have three daisies for every 2 carnations.

Find the slope, if it exists, of the line containing the pair of points.
(8,-6) and (3,9)

Answers

Answer:

The slope is -3

Step-by-step explanation:

the equation for finding the slope between two different points is:

M= (y2-y1)/(x2-x1)

Or in other words the change in y over the change in x.

M= (9+6)/(3-8) = 15/-5 = -3.

(sidenote: I added 9 and 6 for the change in y because you cannot subtract a negative number. Instead you have to add it.)
