This is tricky
lets try substituting y = √)6x - 9)
√(6 - y) + √(6x + y) = √6
squaring both sides:-
6 - y + 6 + y - 2√(6 - y)(6 + y) = 6
12 - 2√(6 - y)(6 + y) = 6
√(6 - y)(6 + y) = (6-12) / -2 = 3
Squaring both sides:-
(6 - y)(6 + y) = 9
36 - y^2 = 9
y^2 = 27
y = +/-√27
√(6x - 9) = +/- 27
6x - 9 = 729
x = 738/6 = 123
This cannot be a solution because we would have a negative value for the
second square root
I would say that no solution exist.
Answer: 36 beans
Step-by-step explanation:
Make a proportion
For every 100 beans, 8 are damaged
8/100
For every 450 brand, x are damaged
x/450
Set the expressions equal to each other
8/100=x/450
100x=3600
Divide by 100 on both sides
x=36
So, out of 450 beans, 36 should be damaged
Hope this helped! :)
Answer:
192
Step-by-step explanation:
so you basically make an equation like this:
4*4(5+7)
4*4(12)
4*48
=192
Answer:
YES its 8
Step-by-step explanation:
Answer:
1. a) The median is 56 because it is the the "middle number and the mean is 75 because if you add them all up and divide them by the number of numbers you get 75.
b) The mean describes it best because it is more accurate as a average.
2. He has an average of 75.6 I got this by finding the mean.
