8 X 2 = 16
Answer:
The equations which represents the situation are
1) 2Y+X=5 and
2) 5X-Y=3
Step-by-step explanation:
Given X= Smaller number and Y = larger number
Therefore the equation for the statement," twice a number added to a smaller number is 5" is 2Y+X=5
and the equation for the statement,"the difference of 5 times the smaller number and the larger number is 3" is 5X-Y=3
Thus the equations which represents the situation are
1) 2Y+X=5 and
2) 5X-Y=3

1) About how much medicine did he make in grams?
Dr. Mann mixed
9.357 g of chemical A,
12.082 g of chemical B,
7.502 g of chemical C
We can determine total amount of medicine that was prepared by Dr. Mann by summing up the chemicals (A,B,C)
=( 9.357grams of A + 12.082grams of B+ 7.502grams of C)
= 28.941 grams in total
The next step is to round up those chemicals value to their nearest tenth as asked by question
Dr. Mann mixed
9.357 g of chemical A= 9.4grams
12.082 g of chemical B,=12.1grams
7.502 g of chemical C =7.5grams
2)Estimate the amount of each chemical by rounding to the nearest tenth of a gram before finding the sum.
Then the sum after rounding up to nearest tenth is
(9.4grams +12.1grams + 7.5grams)
=29 gram
A = L * W = 75 so L = 75/W Cost = 4W + 8(2L + W) = 4W + 16L + 8W = 12W + 16L = 12W + 1200/W C' = (12(W^2 - 100))/(W^2) = (12(W-10)(W+10))/(W^2) so W = 10 then L = 7.5
