Answer:
[tex]x=\frac{5}{11}[/tex]
Step-by-step explanation:
5/2 ÷ x = 11/2
5/2 ÷ x · x = 11/2 · x
5/2 = 11/2x
5/2 ÷ 11/2 = 11/2x ÷11/2
[tex]x=\frac{5}{11}[/tex]
A teacher buys some pencils.
• He buys 2 pencils for each of his students.
• He buys 10 additional pencils.
• Each pencil costs $0.10.
Which equation describes the total amount of money
(y), in dollars, that the teacher spends on pencils as a
function of the number of students (x) he has?
Answers
Answer:
y=2x(.10)
Step-by-step explanation:
I think this is correct but it is 0.10 times 2 because it is 2 pencils/student and each pencil cost 10 cents. We multiply by x because we need to have 2 for each student

Step-by-step explanation:
Finding the interior angles makes the question easier.
The two base angles for b1 are both 125°, and the two base angles for b2 are both 55°.
Because a straight line is 180°, we can find the exterior angles by subtracting the interior angles from 180°.
180°-55° = 125°

Determine the scale factor for A ABC to A A'B'C:
A. 1/2
B. 10
C. 5
D. 2
Answers
The required scale factor of the ΔABC to ΔA'B'C' is 2. Option D is correct.
The scale factor of the ΔABC to ΔA'B'C' is to be determined, while one of each side of the triangle has lengths 5in and 10 in respectively.
The scale factor is defined as the ratio of modified change in length to original length.
Similar triangles are those triangles that have similar properties,i.e. angles and proportionality of sides.
Since the scale factor only applies to similar shapes so as the two triangles are similar then the ratio of the side will describe the scale factor between two triangles.
Scale factor = A'C'/AC
= 10 /5
= 2 in
Thus, the required scale factor of the ΔABC to ΔA'B'C' is 2. Option D is correct.

11. Keng creates a painting on a rectangular canvas with a width that is four inches longer
than the height, as shown in the diagram below.
L= h +4 and H = h
A. Write a polynomial expression, in simplified form, that represents the area of the
canvas.
Keng adds a 3-inch-wide frame around all sides of his canvas.
B. Write a polynomial expression, in simplified form, that represents the total area of the canvas and the frame.
Answers
Part A
Answer: h^2 + 4h-------------------
Explanation:
We multiply the length and height to get the area
area = (length)*(height)
area = (h+4)*(h)
area = h(h+4)
area = h^2 + 4h .... apply the distributive property
The units for the area are in square inches.
===========================================================
Part B
Answer: h^2 + 16h + 60-------------------
Explanation:
If we add a 3 inch frame along the border, then we're adding two copies of 3 inches along the bottom side. The h+4 along the bottom updates to h+4+3+3 = h+10 along the bottom.
Similarly, along the vertical side we'd have the h go to h+3+3 = h+6
The old rectangle that was h by h+4 is now h+6 by h+10
Multiply these expressions to find the area
area = length*width
area = (h+6)(h+10)
area = x(h+10) ..... replace h+6 with x
area = xh + 10x .... distribute
area = h( x ) + 10( x )
area = h( h+6 ) + 10( h+6 ) .... plug in x = h+6
area = h^2+6h + 10h+60 .... distribute again twice more
area = h^2 + 16h + 60
You can also use the box method or the FOIL rule as alternative routes to find the area.
The units for the area are in square inches.
The area of the canvas without the frame is h² + 4h and with frame is h²+16h+60.
What is an area?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
Given that, Keng is painting on a rectangular canvas with a width that is four inches longer than the height,
w = h+4, height = h
Area = (length)x(height)
area = (h+4)x(h)
area = h(h+4)
area = h² + 4h
With the frame,
If we add a 3 inch frame along the border, then we're adding two copies of 3 inches along the bottom side. The h+4 along the bottom updates to h+4+3+3 = h+10 along the bottom.
Keng added a 3-inch-wide frame around the painting,
Therefore,
The h+4 will become h+4+3+3 = h+10
Similarly, along the vertical side = h+3+3 = h+6
Area = (h+10)(h+6) = h²+16h+60
Hence, the area of the canvas without the frame is h² + 4h and with frame is h²+16h+60.

d= second term - first term -- Or 3rd term - 2nd term = 23-14
d=9
T = 14 + (73-1)9
T= 14 + (72)9
T= 14 + 648
T=662.
The 73rd term would be 662.
