Answer:
The middle two expressions shown are not polynomials
Step-by-step explanation:
Polynomial terms have positive integer exponents on any variables. A 2/3 power is not an integer exponent. Division by y is equivalent to an exponent of -1, which is not a positive integer.
Answer:
5 5/7 acres
Step-by-step explanation:
The product is ...
(2 1/7 acres/section)(2 2/3 sections) = (15/7)(8/3) acres = 40/7 acres
= 5 5/7 acres
The farmer owns 5 5/7 acres of land.
4x+6y=8
3x+y=9
y = 9 - 3x
4x + 6(9-3x) = 8
4x + 54 - 18x = 8
14x = 46
x = 23/7
y = 9 - 3(23/7)
y = 9 - 69/7
y = - 6/7
120 grams half life at 45 days would be 60 then half life of 60 in another 45 days (90 total) should be 30 grams
