Find the complete question
Zelie planned for a square pool to have a side length of 28 ft but found that it needs to be 14 ft long to fit in her backyard. She found the change of scale below.
Which is Zelie’s error?
Zelie should have divided both numbers by 14.
Zelie should have written the ratio as 28/7.
Zelie should have written the ratio as 14/8.
Zelie should have subtracted 14 from both numbers.
Original length of pool = 28ft
If he found that it need to be 14ft longer then the actual measure = 14th
given equation is;
(28 - 7)/14 - 7 = 14/7
Scale constant = original length/actual length
Scale constant = 28/14
Scale constant = 2
Hence the scale constant is 2
According to the option, Zelei should have divided both numbers by 14.
Answer: Part A the answer is yes and Part B the answer is no.
Step-by-step explanation:
Part A when you divide 7 by 2 you get 3.5 and if you multiply that number by the rest of the numbers and you get the number beneath the other number.
Part B when you divide 8 by 5 you get 1.6 and if you multiply that number by the rest of the numbers and then you don't get the number beneath the other number.
Danche!
I did the math and I think that it's 3.7
Let the numbers be X and X+1.
X+2(X+1)=29
X+2X+2=29
3X=29-2
X=27/3
X=9.
Thus, the Numbers are therefore 9 and 9+1=10
i.e 9 & 10.
Thus, when 9 is added to (2*10=20), the result is 29.
Answer:
36
