- Can a whole number be 5 more than another number and
also 5 times as many as the other number? Give an example
to explain your answer.
Answer:
Nope
Step-by-step explain
1+5=6
6/5 is not 1
2+5=7
7/5 is not 2
NO, a whole number can't be 5 more than another number, & 5 times another number.
Let a whole number be = n
5 more than whole number = n + 5 ; And 5 times the whole number = 5n
Equating them , n + 5 = 5n
5n - n = 5
4n = 5
n = 5 / 4
5 / 4 is not a whole number, as it is in fractional form.
Also, 5/4 + 5 = (5 + 20) / 4 = 25 / 4
5 / 4 x 5 = 25 / 4
Both above sum & product are also in fractional form, so are not whole numbers.
Hence proven.

I just need the ratio and the explanation, Lin, Diego, and Elena are competing to see who can finish their book the fastest.
Lin read the first 54 pages from a 270-page book in the first 3 days.
Diego read the first 100 pages from a 320-page book in the first 4 days.
Elena read the first 160 pages from a 480-page book in the first 5 days.
If they continue to read every day at these rates, who will finish first, second, and third? Explain or show your reasoning:
Answer: The answer to your question is:
1st Diego
2nd Diego and Elena ( both 15 days)
Step-by-step explanation:
Data
Lin 54 pages 270-page book 3 days
Diego 100 pages 320 page 4 days
Elena 160 pages 480 page 5 days
Process
Lin
54 pages ------------------- 3 days
270 page ----------------- x
x = (270 x 3) / 54
x = 15 days
Diego
100 pages ----------------- 4 days
320 -------------------- x
x = (320 x 4) / 100
x = 12.8 days
Elena
160 pages ------------------- 5 days
480 pages -------------------- x
x = (480 x 5) / 160
x = 15 days

The table shows the attendance at the art show for the past week.
What does the attendance need to be on Saturday to have an average attendance for the week of 30 people per day?
Answer: The correct answer is - 50.
Step-by-step explanation: :)
Answer:
50
Step-by-step explanation:
To calculate the mean, we do the total divided by the number of values. Therefore, to get 30, with 7 values, we need to have a total of 210. Currently, we have a total of 160, so Saturday needs to be 50, because 210-160=50.

A triangle has an area of 15. One of its sides has length 10. What is the length of the altitude to that side?
Answer:
Altitude = 3
Step-by-step explanation:
Given the area of a triangle as 15, with a length of 10:
We can use the following formula for finding the area of a triangle:
Area (A) = ½bh
Where:
Base (b) = 10
Height (h) or altitude = unknown
Substitute the given values into the formula:
Area (A) = ½bh
15 = ½(10)h
15 = 5h
Divide both sides by 5 to solve for h:
[tex]\displaystyle\mathsf{\frac{15}{5}\:=\:\frac{5h}{5} }[/tex]
h = 3
Therefore, the length of the altitude or height of the given triangle is 3.
