Select the three equations that are equivalent to the equation 3x−4=5.

1. 3x = 9

2. 3x - 4 + 4 = 5 + 4

3. x = 9

4. x - 4 = 2

5. -4 = 5 - 3x

Answers

Answer 1

Hey there!

Solving

3x - 4 = 5

Add 4 to both sides

3x - 4 + 4 = 5 + 4

3x = 9

x = 9/3

x = 3

Equivalent expressions are:

1. 3x = 9

2. 3x - 4 + 4 = 5 + 4

3. 4 = 5 - 3x

If you're confused about the last one

Solving

−4=5−3x

Step 1: Simplify both sides of the equation.

−4=5−3x

−4=5+−3x

−4=−3x+5

Step 2: Flip the equation.

−3x+5=−4

Step 3: Subtract 5 from both sides.

−3x+5−5=−4−5

−3x=−9

Step 4: Divide both sides by -3.

−3x/−3 = −9/−3

x=3 (Still the same answer)

Answer 2
1. 3x = 9
2. 3x -4+4 = 5+4
5. -4 = 5 -3x

These would all be different forms of the equations if you used different order of operations

2. You are building a fence around your vegetable garden in your backyard. If
the garden is 12'8" long and 4'6" wide, what is the total length of fencing you
will need?

Answers

The length of fencing required is 34.34 feet.

Data;

Length = 12 feet 8 inch long = (12 + 0.67) feet = 12.67 feetWidth = 4 feet 6 inch wide = (4+0.5)feet = 4.5 feet

Perimeter of the Garden

To find the total length of fencing required, we have to find the perimeter of a rectangle since the garden has a rectangular shape.

[tex]P = 2(L + W)[/tex]

We can substitute the values in the formula of perimeter above and proceed to solve.

[tex]P = 2(L+W) \\P = 2(12.67 + 4.5) \\P = 2(17.17)\\P = 34.34ft[/tex]

You make commission working at Footlocker. On Saturday you sold

Sunday you sold $1,300 worth of merchandise. If you made the same percent commission,how much did you earn on Sunday?


A. $8

B. $86. 66

C. $104

D. $1,039. 99

Answers

Answer:

C. $104

Step-by-step explanation:

First, we need to figure out what percent $120 is of $1500.

120 ÷ 1500 = 0.08 = 8%. So, $120 is 8% of $1500, and this is the percentage that'll be used to calculate Sunday's commission.

0.08 (8%) × 1300 = 104

Thus, you earned $104 on Sunday.

For a given input value n, the function h outputs a value mmm to satisfy the following equation.

Write a formula for h(n) in terms of n.

Answers

Considering the equation given, the formula for h(n) in terms of n is given by:

h(n) = -2n - 13

What is the equation?


The equation given is:

m + 1 = -2(n + 6).

We want to write m as a function of n, hence:

m + 1 = -2(n + 6).

m = -2n - 12 - 1

m = -2n - 13

Find an equation for the plane that contains the line and is perpendicular to the plane

Answers

For the line and the plane to be perpendicular, they have to meet at right angles

The equation for the plane is x + 2y + 3z= 26

How to determine the equation?

From the complete question, we have:

Point = (5,0,7)

Plane perpendicular to ⟨1,2,3⟩

The general equation is:

a * x+b * y+c * z = d

So, we have:

d = 5 * 1 + 2 * 0 + 7 * 3

Evaluate

d = 26

Recall that:

d = 5 * 1 + 2 * 0 + 7 * 3

Replace the points with x, y and z.

So, we have:

d = x * 1 + 2 * y + 3 * z

Evaluate

d = x + 2y + 3z

So, we have:

d = x + 2y + 3z and d = 26

Equate both equations

x + 2y + 3z= 26

Hence the equation for the plane is x + 2y + 3z= 26

To solve for x and y, take advantage of the relationships between angles and diagonals in a rhombus. Each diagonal bisects the vertex angle, and the acute angles in each right triangle are complementary.

__

The angles created by the diagonal at the lower left vertex are congruent:

  y° = 21°

Answers

The function [tex]y = -5t^2 + 125[/tex] of the nickel is quadratic function

It will take 5 seconds for the coin to hit the ground

How to determine the time the nickel hits the ground?

The function is given as:

[tex]y = -5t^2 + 125[/tex]

When the nickel hits the ground, the value of the function is:

y = 0

So, we have:

[tex]-5t^2 + 125 = 0[/tex]

Subtract 125 from both sides

[tex]-5t^2 =- 125[/tex]

Divide both sides by -5

[tex]t^2 =25[/tex]

Take the square root of both sides

[tex]t = 5[/tex]

Hence, it will take 5 seconds for the coin to hit the ground

Mrs. Orrie surveyed all classes that he teaches about the three different types of music thay students most listen to. His findings are displayed in the Venn diagram below.

Part A: Determine the probability that a student will like Top-Hits.

Part B: Determine the probability that a student will like country or R&B.

Part C: Determine the probability that a student will not like all three generes of music.

Answers

Using the probability concept, it is found that there is a:

A. 0.5116 = 51.16% probability that a student will like Top-Hits.

B. 0.7907 = 79.07% probability that a student will like country or R&B.

C. 0.9186 = 91.86% probability that a student will not like all three generes of music.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

According to the Venn diagram, there is a total of 18 + 8 + 11 + 7 + 24 + 1 + 17 = 86 students.

Item a:

18 + 11 + 7 + 8 = 44 like top hits, hence:

p = 44/86 = 0.5116.

0.5116 = 51.16% probability that a student will like Top-Hits.

item b:

24 + 11 + 7 + 1 + 17 + 8 = 68 like country of R&B, hence:

p = 68/86 = 0.7907.

0.7907 = 79.07% probability that a student will like country or R&B.

Item c:

Only 7 like all three, hence 86 - 7 = 79 do not.

p = 79/86 = 0.9186.

0.9186 = 91.86% probability that a student will not like all three generes of music.

What is cost price per pound?

The cost price per pound is the amount of money required to buy one pound of a brand or goods.

To find the cost price per pound, divide the total amount of cost of the goods to the total number of goods.

At one farmer’s market, bananas cost $0.80 per pound.

At another farmer’s market, bananas are sold in 5-pound bags for $4. 50 per bag. To compare it with first market price, divide the 5 pound bags with $4.50.

The cost of one bag in this market is,

[tex]C=\dfrac{4.50}{5}\\C=0.5625[/tex]

As this cost is less, thus, the cost of this market for one banana is less than the first market and so this is the better buy.

Hence, to find the better buy divide 4.50 by 5 to find the unit rate for the 5-pound bag, and compare that number to $0. 80 per pound.

No archer ever lived that could speed a gray goose shaft with such skill and cunning as his, nor were there ever such yeomen as the sevenscore merry men that roamed with him through the greenwood shades. Right merrily they dwelled within the depths of Sherwood Forest, suffering neither care nor want, but passing the time in merry games of archery or bouts of cudgel play, living upon the King's venison, washed down with draughts of ale of October brewing.Not only Robin himself but all the band were outlaws and dwelled apart from other men, yet they were beloved by the country people round about, for no one ever came to jolly Robin for help in time of need and went away again with an empty fist.And now I will tell how it came about that Robin Hood fell afoul of the law.When Robin was a youth of eighteen, stout of sinew and bold of heart, the Sheriff of Nottingham proclaimed a shooting match and offered a prize of a butt of ale to whosoever should shoot the best shaft in Nottinghamshire. "Now," quoth Robin, "will I go too, for fain would I draw a string for the bright eyes of my lass and a butt of good October brewing."
