Answer:
I agree with you that step 5 doesn't make sense.
In step 4 he had accurately determined that there were 216 British and Indian stamps.
B = number of British stamps
N = number of Indian stamps (using N because "I" looks too much like a "1")
B + N = 216
3/5B = N
substitute for N:
B + 3/5B = 216
8/5B = 216
divide both sides of the equation by 8:
1/5B = 27
multiply both sides of the equation by 5:
B = 135
N = 81
It appears that step 5 is missing the "multiply by 5".

Reason quantitatively. A local bakery sells bagels
for $0.90 each. Consider a function for which the
input is the number of bagels purchased and the
output is the total cost of the bagels. What are the
domain and range in this situation? Explain.
Philip's Bagel Shop recently sold 18 bagels, of which 9 were whole wheat bagels. Considering this data, how many of the next 14 bagels sold should you expect to be whole wheat bagels?

A line that passes through (-1, 6) and the origin
Answer: The equation is y = -6*x
Step-by-step explanation:
I suppose that we want to find the equation for a line that passes through the point (-1, 6) and the origin (remember that the origin is the point (0,0))
A general linear equation is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If this line passes through the points (x₁, y₁) and (x₂, y₂), then the slope of the line is equal to:
a = (y₂ - y₁)/(x₂ - x₁)
Now we know that our line passes through the points (0, 0) and (-1, 6), then the slope is:
a = (6 - 0)/(-1 - 0) = 6/-1 = -6
Then our equation is something like:
y = -6*x + b
To find the value of b we can use the fact that this line passes through the point (0, 0).
This means that when x = 0, y is also equal to zero.
If we replace these values in the equation we get:
0 = -6*0 + b
0 = b
Then our equation is:
y = -6*x

The total area of three walls, each 8' feet high; 14, long, and other is 10' long?
Answer:
304 feet²
Step-by-step explanation:
Given three walls :
First wall : 8 feets high ; 14 inches long
Second wall : 8 feets high ; 14 inches long
Third wall : 8 feets high ; 10 feets long
Area = Length * height
Area = (8 * 14) = 112 ft²
Area = (8 * 14) = 112 ft²
Area = (8 * 10) = 80 ft²
Total area :
(112 + 112 + 80) ft²
= 304 feet²
Topic: Similar Triangles
Determine whether the triangles are similar by AA ~, SSS ~, SAS~, or not similar. If the triangles are similar, write a valid similarity statement.
Answer:
The triangles are not similar
Step-by-step explanation:
The ratios of the 2 triangles are not equivalent to each other so the triangles are not proportional. Since the triangles are not proportional, the triangles are not similar.
16/26= 8/13
21/32= 21/32
Plus, you can't determine if the triangles are similar by SAS and SSS since the problem doesn't give you enough information.
Hope this helps! :)

the mean of 16,18,x,12 and 15 calculate the value of x
Answer:
29
Step-by-step explanation:
Mean = sum of datas/Sample size
Given the data 16,18,x,12 and 15
Sum = 16+18+x+12
Sum = 46+x
Mean = 15
Sample size = 5
Substitute
15 = 46+x/5
15 * 5 = 46+x
75 = 46 + x
x = 75-46
x = 29
Hence the value of x is 29

Help pls show work if needed!
Answer:
d = 50h
Step-by-step explanation:
We are using the linear property y = mx.
We know that distance = rate × time, so if we subsitute this, we get that the distance is d, the rate is 50 mph, and the time is h.
Therefore, we can form the equation d = 50h.

THE amusement park won't allow kids to ride roller-coasters until they are a minimum of 48 inches tall. Michael is now 42 inches tall, and grows about 1/2 inch every month. How many months will it be until Michael can read a roller coaster? Please show me the individual steps?
Answer: It will one year (or 12 months) before Michael is able to ride the roller coaster.
Step-by-step explanation: Because he grows a half inch every month, this means that It takes him two months to grow one full inch. Because he has to grow six inches, you just multiply 2 by 6 to get 12 months or one year.
Answer:
48-42=6, which is how much Michael needs to grow.
1/2x=6, where x is the number of months
x = 12 months.
1 year = 12 months so the answer is one year.
