7 pens at $x is 7x
5 pens at $(2x+3) is 5(2x+3)
y pens at $6 is 6y
(3y-1) pens at $10 each is 10(3y-1)
All together the cost expression is 7x + 5(2x+3) + 6y + 10(3y -1).
Simplify by applying the distributive property and combine like terms.
7x + 10x + 15 + 6y + 30y - 10
17x + 36y + 5

3. Mrs. LeBlanc is making a Pokémon box. The length of the box is 12 inches greater than its width, and its height is 5 inches less than its width. Find the dimensions of the Pokémon box formed, given that its volume is 9600 cubic inches. (Show all work including setting up the equation, simplifying the equation, listing the possible rational roots, testing the possible rational roots using synthetic division, and then identifying all of the dimensions.
Answer:
The width is 20 inches, the length is 32 inches and the height is 15 inches.
Step-by-step explanation:
Let x inches be the width of the box. If the length of the box is 12 inches greater than its width, then the length of the box is x+12 inches. If the height of the box is 5 inches less than its width, then the height of the box is x-5 inches.
The volume of box is
[tex]V=\text{length}\cdot \text{width}\cdot \text{height}\ in^3.[/tex]
Therefore,
[tex]9600=x\cdot (x+12)\cdot (x-5).[/tex]
Solve this equation:
[tex]x(x^2+12x-5x-60)=9600,\\ \\x^3+7x^2-60x-9600=0.[/tex]
The integer solutions of this equation can be among the divisors of -9600. The divisors of 9600 are:
[tex]\pm1, \pm2, \pm3, \pm4,\pm5,\pm6,\pm8,\pm10,\pm12,\pm15,\pm16,\pm20,\pm24,\pm25,\pm30,\pm32,....[/tex]
We can check all these divisors and see that x=20 is a solution, then using synthetic division
[tex]x^3+7x^2-60x-9600=(x-20)(x^2+27x+480).[/tex]
Since the quadratic factor has discriminant [tex]D=27^2-4\cdot 480=-1191<0,[/tex] we can state that the only solution is x=20 inches. The width is 20 inches, the length is 32 inches and the height is 15 inches.

What is the percent of decrease from 10 to 3?
Write your answer using a percent sign (%).
The percent of decrease from 10 to 3 can be calculated by finding the difference between the two numbers, dividing this difference by the original number, and multiplying the result by 100. This method gives us a decrease of 70%.
Explanation:The question is looking to find the percent of decrease between two numbers, specifically from 10 to 3. To calculate this, we first find the difference between the two numbers (which is 10 - 3 = 7), then divide this difference by the original number (7 divided by 10 equals 0.7) and finally multiply the result by 100 to convert it to percentage form. This gives us a 70% decrease.
Here are the step-by-step calculations:
Find the difference between the two numbers: 10 - 3 = 7.Divide the difference by the original number: 7 / 10 = 0.7.Multiply the result by 100 to convert to a percentage: 0.7 x 100 = 70%.So, the decrease from 10 to 3 is 70%.

ABEF=CBED. The perimeter of CBED is 17. Find the length of BE
2.7. Because of the CPCTC theorem, like CB is equal to 5.9 so if you add the lengths of CB, CD, and ED and subtract this by 17, you find the length of BE which is 2.7
Answer:
Option B, 2.7 is the answer.
Step-by-step explanation:
Perimeter of CBED = CD + ED + BC + BE
17 = 5.6 + 2.8 + 5.9 + BE
[Since ABEF ≅ CBED so AB = BC = 5.9]
Now 17 = 14.3 + BE
BE = 17 - 14.3
= 2.7
Therefore, Length of BE = 2.7
Option B, 2.7 is the answer.

In ΔVWX, the measure of ∠X=90°, XV = 27 feet, and WX = 57 feet. Find the measure of ∠V to the nearest degree.
Answer:
[tex]<V=65\°[/tex]
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
In the right triangle VWX
[tex]tan(V)=\frac{WX}{XV}[/tex] -----> opposite side angle V divided by the adjacent side angle V
substitute the values
[tex]tan(V)=\frac{57}{27}[/tex]
[tex]<V=arctan(\frac{57}{27})=65\°[/tex]
Final answer:
To find the measure of ∠V, we take the ratio of XV to WX (opposite to adjacent side) and use the tangent function. By calculating tan(∠V) = 27/57 and taking the inverse tangent, we get ∠V ≈ 25° to the nearest degree.
Explanation:
To find the measure of ∠V in ∆VWX, where ∠X=90°, XV = 27 feet, and WX = 57 feet, we use the trigonometric ratios, specifically the tangent function, since we are dealing with a right-angled triangle and we have the lengths of the opposite side (XV) and the adjacent side (WX) to ∠V.
Step by Step Solution:
Use the definition of the tangent function: tan(∠V) = opposite/adjacent.
Substitute the known values: tan(∠V) = XV/WX = 27/57.
Calculate tan(∠V) = 0.4737.
Find the angle whose tangent is 0.4737 using an inverse tangent function on a calculator: ∠V ≈ 25° (to the nearest degree).
Therefore, the measure of ∠V is approximately 25°.

If y = 2x - 1 and (3, 5) and (4, 7) are part of the pattern then what is the y coordinate of (5, __ )? A) 8 B) 9 C) 10 D) 11
Answer:
(5, 9)
Step-by-step explanation:
Substitute the x- coordinate of the point into the equation to evaluate the y- coordinate, that is
x = 5 : y = (2 × 5 ) - 1 = 10 - 1 = 9 → B
Hence the coordinates of the point are (5, 9 )
Final answer:
Using the equation y = 2x - 1, the y-coordinate for the point (5, __) is calculated to be 9 by substituting x = 5 into the equation, resulting in the value that fits the identified pattern.
Explanation:
The question asks for the y-coordinate of the point (5, __) based on the pattern described by the equation y = 2x - 1. We see that the given points (3, 5) and (4, 7) fit this pattern, as plugging x = 3 into the equation gives y = 2(3) - 1 = 5, and plugging x = 4 into the equation gives y = 2(4) - 1 = 7. To find the y-coordinate for the point where x = 5, we can follow the same arithmetic pattern.
Using the equation, we plug in x = 5:
y = 2(5) - 1
= 10 - 1
= 9
Therefore, the y-coordinate for the point (5, __) is 9, which corresponds to option B.

the angle of elevation from mindy to a cell phone tower is 75. if mindy is standing 28 feet from the base of the tower, find the height of the tower
A) 104.5 ft
B) 105.8 ft
C) 106.1 ft
D) 107.4 ft
E) 108.9 ft
Final answer:
To find the height of the tower given the angle of elevation and distance from the observer to the tower's base, the tangent function is used. The height is calculated as 28 feet multiplied by tan(75 degrees), resulting in approximately 105.8 feet.
Explanation:
The student is asking for help with a trigonometry problem involving the angle of elevation to calculate the height of a tower. In this case, we are given the angle of elevation as 75 degrees and the distance from Mindy to the base of the tower as 28 feet. To find the height of the tower, we use the tangent function, which is the ratio of the opposite side to the adjacent side in a right-angled triangle.
So, we have:
tan(75 degrees) = opposite/adjacent
tan(75 degrees) = height of tower/28 ft
Therefore, to find the height of the tower, we can write this equation as:
height of tower = 28 ft × tan(75 degrees)
By calculating this using a calculator, we find the height of the tower to be approximately 105.8 feet, which corresponds to option B.
