So,
This is simple multiplication once you've converted the percentage to a decimal.
236.4% = 2.364
Multiply 2.364 by 180.
2.364 * 180 = 425.52 lbs.
Neil Armstrong's space suit would weigh 425.52 lbs. on Jupiter.
Answer:
(x, y) = (1/2, -1)
Step-by-step explanation:
Subtracting twice the first equation from the second gives ...
(2/x +1/y) -2(1/x -5/y) = (3) -2(7)
11/y = -11 . . . . simplify
y = -1 . . . . . . . multiply by y/-11
Using the second equation, we can find x:
2/x +1/-1 = 3
2/x = 4 . . . . . . . add 1
x = 1/2 . . . . . . . multiply by x/4
The solution is (x, y) = (1/2, -1).

<em>Additional comment</em>
If you clear fractions by multiplying each equation by xy, the problem becomes one of solving simultaneous 2nd-degree equations. It is much easier to consider this a system of linear equations, where the variable is 1/x or 1/y. Solving for the values of those gives you the values of x and y.
A graph of the original equations gives you an extraneous solution of (x, y) = (0, 0) along with the real solution (x, y) = (0.5, -1).
The area of the circular flower bed
=(13÷2)^(2 × pie
≈132.73 sq.feet
the amount of fertilizer needed
132.73÷10
=13.273
Thus 14 bags of fertilizer will be needed
