<span>This problem is an
example of ratio and proportion. A ratio is a comparison between two different
things. You are given the time of about 26.1 seconds to fold 1
shirt. Also you are given 48 shirts. You are required to find the time
in seconds to fold 48 shirts. The solution of this problem is,</span>
<span>
26.1 seconds /1
shirt = time/ 48
shirts</span>
<span>time = (48 shirts)
(26.1 seconds /1 shirt)</span>
<span>time<u> = 1,252.8
seconds</u></span>
<u>The time
it takes to fold 48 shirts is 1,252.8 seconds.</u>
Answer:
20 and 56
Step-by-step explanation:
76/2 = 38
38 - 18 = 20
38 + 18 = 56
20 + 56 = 76
Let the number of corn acres be xx and the number of wheat acres be yy.
We are given that:
1- The total number of acres is 180, this means that:
xx + yy = 180 ..............> equation I
2- The number of corn acres is 3 times that of wheat. This means that:
xx = 3yy .........> equation II
Substitute with equation II in equation I to get the value of yy as follows:
xx + yy = 180
3yy + yy = 180
4yy = 180
yy = 45 acres
Now substitute with yy in equation II to get xx as follows:
xx = 3yy
xx = 3*45
xx = 135 acres
Based on the above calculations:
acres of corn = xx = 135 acres
acres of wheat = yy = 45 acres
The property that is not a justification for the proof is: B. addition property of equality.
<h3>What is the Addition Property of Equality?</h3>
According to the addition property of equality, if a - b = c, then a - b + b = c + b, which is: a = c + b.
In the proof given, there is no single statement that shows that we are adding a figure or variable to both sides of any equation, therefore, the justification that is not part of the proof is: addition property of equality.
