Answer:
18x+21
Step-by-step explanation:
First multiply each equation by 2 since there is 2 sides for both the length and width.
2(2x+3) 2(7x+9)
4x+3 14x+18
Then combine like terms
4x+14x 3+18
18x 21

Ann, Claire, and Josh collect stickers. One week, Ann collects 7 more stickers than Josh. Josh collects twice as many stickers as Claire. If they collect a total of 157 stickers, how many stickers did each collect?
Answer:
Claire = 30 stickers
Josh = 60 stickers
Ann = 67 stickers
Step-by-step explanation:
Let
Claire stickers= x
Josh = 2x
Ann= 2x + 7
Total stickers = 157
Total stickers = Claire stickers + Josh stickers + Ann stickers
157 = x + (2x) + (2x+7)
157 = x + 2x + 2x + 7
157 = 5x + 7
Subtract 7 from both sides
157 - 7 = 5x + 7 - 7
150 = 5x
Divide both sides by 5
150/5 = x
30 = x
x = 30
Claire stickers= x
=30 stickers
Josh = 2x
= 2(30)
= 60 stickers
Ann= 2x + 7
= 2(30) + 7
= 60 + 7
= 67 stickers
Claire = 30 stickers
Josh = 60 stickers
Ann = 67 stickers
Gianna is taking a multiple choice test with a total of 100 points available. Each question is worth exactly 5 points. What would be Gianna's test score (out of 100) if she got 3 questions wrong? What would be her score if she got xx questions wrong?
Answer:
Her test score would be an 85 because 5x3=15 and then you would subtract 15 from 100 which would be 85
equation would be x=100-(5y)
Answer:
[tex]85[/tex]
Step-by-step explanation:
Let [tex]x[/tex] equal the number of questions.
Let's find how many total questions there are:
[tex]100=5x[/tex]
Divide by the coefficient of [tex]x[/tex], which in this case is [tex]5.[/tex]
[tex]20=x[/tex]
So we have a total of [tex]20[/tex] questions, each are worth [tex]5[/tex] points.
Now, Gianna got [tex]3[/tex] questions wrong, and if we know there are [tex]20[/tex] total questions...
[tex]20-3[/tex]
Solve.
[tex]20-3=17[/tex]
So we know Gianna got [tex]17[/tex] questions correct.
Let's use an expression to figure out her score.
Again, let [tex]x[/tex] equal the number of questions.
[tex]5x[/tex]
Substitute.
[tex]5(17)[/tex]
Multiply.
[tex]85[/tex]

The graph shows the function representing the recommended amount of mulch, in cubic yards, for circular flowerbeds based on the radius of the flowerbed in feet. If the vertex of the function is at the point (0, 0.5), what is the recommended amount of mulch for a flowerbed with a radius of 20 feet? Round to the nearest tenth if necessary. 7 cubic yards 13 cubic yards 25.5 cubic yards 31 cubic yards
Answer:
B, 13 cubic yards.
Step-by-step explanation:
You didn't give a graph, but I'm assuming you had the same question as me (I attached the graph that I had). I took the test and got the right answer.
The recommended amount of mulch for a flowerbed with a radius of 20 feet is 13 cubic yards
How to determine the recommended amount of mulch?The vertex of the graph is given as:
Vertex = (0,0.5)
The equation of the graph is given as:
[tex]y = 0.5 * 1.177^x[/tex]
When the radius is 20 feet, we have:
y = 0.5 * 1.177²⁰
Evaluate
y = 13.02
Approximate
y = 13.0
Hence, the recommended amount of mulch for a flowerbed with a radius of 20 feet is 13 cubic yards

Step-by-step explanation:
A rational number can be expressed in the form

From the set
3 is rational as it can be expressed as [tex]\frac{3}{1}[/tex]
and [tex]\sqrt{9}[/tex] = 3 ← rational

2(x – 7) = 5x + 4 can someone help me out
Answer:
x = -6
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
2(x - 7) = 5x + 4
Step 2: Distribute parenthesis
2x - 14 = 5x + 4
Step 3: Subtract 2x on both sides
-14 = 3x + 4
Step 4: Subtract 4 on both sides
-18 = 3x
Step 5: Divide both sides by 3
-6 = x
Step 6: Rewrite
x = -6
Answer:
x=-6
Step-by-step explanation:
2(x-7)= 5x+4
2x - 14 = 5x+4
-2x -2x
-14 = 3x +4
- 4 -4
-18= 3x

Maria designs and sells bowling uniforms. She charges a design fee of $8 for a custom bowling shirt, and sells each shirt for $25 dollars. (a) Write an equation in slope-intercept form, where y represents the total cost and x represents the number of bowling shirts.
Answer:
y = 25x + 8
Step-by-step explanation:
The slope intercept equation has a standard form of;
y = mx + c
Now, we are told that She charges a design fee of $8 for a custom bowling shirt, and sells each shirt for $25 dollars.
And that y represents the total cost and x represents the number of bowling shirts.
Now, since x represents the number of bowling shirts, the cost of x bowling shirts is = 25x
Also, since design fee is $8, it means that total cost = 25x + 8
Writing this in slope intercept form;
y = 25x + 8

What is the length of the x-component of the vector shown below?
Answer:
13.91
Step-by-step explanation:
The question lacks the required diagram. Find the diagram attached.
From the diagram the length of the vector along x component is given as:
Vx = Vcos(theta)
theta is the angle between the vector and the x axis
V is the length of the vector
Given
theta = 22°
V = 15
Substitute the given values into the formula above
Vx = 15cos22°
Vx = 15×0.9272
Vx = 13.91
Hence the length of the x-component of the vector is approximately 13.91

5.5% of x =19.84
find x
Answer: 360.73
Step-by-step explanation:
When you come across any question that says [a of b] is just saying a × b.
5.5% of x=5.5% × x
-----------------------------------------------------------------
Given
5.5% of x=19.84
Converted into numerical expression
5.5% × x=19.84
Divide both sides by 5.5% (0.055)
x=19.84 ÷ 5.5%
simplify
x=360.73 (rounded)
Answer:
360.7273
Step-by-step explanation:
5.5% of 'x' is 19.84
so, x*5.5/100 = 19.84
or, x*5.5 = 1984
or, x = 1984/5.5
so, x=360.7273(answer)

Which equation shows that 6 is a factor of 18?
Choose 1 answer:
A- 18 = 6 x 12
B- 18 = 24 - 6
C- 3 = 18 : 6
D- 6 = 18 x 3
To see if 6 is a factor of 18, we need to take the quotient between 18 and 6 and see if it is an integer, so the correct option is C.
How to know when a number is a factor of another number?
We say that the number a is a factor of b if and only if a divides b.
This means that the quotient:
b/a = integer number.
Then, to see if 6 is a factor of 18, we need to divide 18 by 6, and see if the quotient is an integer number.
We will get:
18/6 = 3
3 is an integer number, so yes, 6 is a factor of 18.
From this, we can conclude that the correct option is C.

Jim was offered a job as a computer programmer making 65K per year. Another company offered Jim a position earning $1,800 a week. What job pays more?
Answer:
since second company salary, $93,600, is more than first company yearly salary of $65000
Second company pays more
Step-by-step explanation:
To check what job pays more we have to compare yearly salary of both the company offer.
_________________________________________________
Yearly salary from one company = 65k = 65000
Weekly salary from another company = $1800
there are 52 weeks in a year
to get yearly salary , we need to multiply weekly salary with 52.
Yearly salary from another company = Weekly salary*no of wees in a year
Yearly salary from another company = 52*$1800 = $93,600
since second company salary, $93,600, is more than first company yearly salary of $65000
Second company pays more

square of the radius plus twice the product of it, the radius, and the height.
Education
Financial Algebra, F

Step-by-step explanation:
The cylinder is a closed figure which consists of two circular ends. If r is the radius and h is the height of the cylinder, then its surface area is given by :
[tex]A=2\pi rh[/tex]
or
[tex]A=2\pi \times r\times h[/tex]
We also know that, surface area = perimeter×height
So, the surface area of the cylinder is the product of circumference of the circle and height of the cylinder.
