ASSUME THAT S/A= 4.5, D/A= 4.5, N/E= .80 AND A=D+E SLOVE FOR N/S.
Well, from the first two, D=S
and D=4.5A
From the fourth,
A=D+E=4.5A+E
or E=-3.5A
But N=.8E, so N=.8*(-3.5A)
solve for N/S is the same as N/D
N/s=N/D=.8*(-3.5A)/4.5A
and surely you can finish it.
is -.62 correct
It is if you checked my work and found no errors.
To solve for N/S, we first need to rewrite the equation A = D + E in terms of N and S.
Given:
S/A = 4.5
D/A = 4.5
N/E = 0.80
Let's start by solving for A:
From S/A = 4.5, we can rearrange the equation to get A = S/4.5.
Similarly, from D/A = 4.5, rearranging the equation gives A = D/4.5.
Since A = D + E, we have two equations for A:
1) A = S/4.5
2) A = D/4.5
Since both equations equal A, they must be equal to each other:
S/4.5 = D/4.5
We can then cancel out 4.5 from both sides:
S = D
Now, we can solve for N/S:
N/E = 0.80
Since S = D, we can replace E with S in the equation:
N/S = 0.80
Thus, the solution for N/S is 0.80.
