Answer:
Tyler is right
Step-by-step explanation:
Given that:
Lenght of wooden plank used = 3.5 feets
Placement of tick marks = 1 1/3 inches apart
Number of tick marks placed = 20
Recall:
1 foot = 12 inches
Hence, length of wooden post in inches :
3.5 * 12 = 42 inches on length
Total length covered by the ticks placed :
1 1/3 inches * Number of ticks placed
1. 333 * 20 = 26.6667 inches
Unmarked length = length of post - length covered by tickmark
Unmarked length = (42 - 26.6666) inches
Unmarked length = 15.3333 inches.
Hence,
Within 15 - 16 inches are yet to be marked.
By the additive property of equality, the equations John wrote are equivalent.
<h3>Additive property of equality: Determining equivalent equations</h3>
From the question, we are to determine if the equations John wrote are equivalent.
From the given information,
John wrote that
5 + 5 = 10
Then,
He added n to both sides of the equation to get
5 + 5 + n = 10 + n
From the Additive property of equality, we have that
"<em>If we add or subtract the same number to both sides of an equation, the sides remain equal</em>."
Since, John added the same number, n, to both sides of the equation, the equations John wrote are equivalent.

= Ratio of minutes to miles in which Samuel drove = 28 : 32
= Ratio of minutes to miles in which Beverly drove = 42 : 48
To find whether the time they drove and the distance they covered were proportional or not , let us first change them into a fraction and then simplify them .
= 28 : 32 = 28/32
= 28/32
Both the numerator and the denominator is divisible by 4 .
= 28 ÷ 4 / 32 ÷ 4
= 7/8 = 7 : 8
Samuel = 7 : 8
Beverly = 42 : 48 = 42/48
= 42/48
Both the numerator and the denominator is divisible by 6 .
= 42 ÷ 6 / 48 ÷ 6
= 7/8
Therefore, the ratio of miles to minutes drove by Samuel and Beverly is proportional , 7:8 :: 7:8
