Answer:
usually right now for me tax is 13% so when i and then i usually multiply by 1.13 to give me the total which would be the same for you so you need to multiply by 1.07 which is essentially c.
therefore c is the answer
Hm maybe look up the name of the document and put pdf answers
Is this rsm? lol okay.
x is the amount of money invested at 5%
y is the amount of money invested at 6%
the total amount of money invested is $6000, or x+y
when it says the yearly income is $337.50, it means that the 5% of x plus the 6% of y equals $337.50.
now write the two equations:
x+y =6000
0.05x + 0.06y = 337.50
now, find y for the first equations, which is y= 6000 - x. use this equation to substitute for the second equation.
0.05x + 0.06(6000 -x) = 337.50
blah, blah, blah, solve for x... you should get x = 2250, and y = 3750.
I hate money problems like this, hope it helps.
Answer:
f=1/x^2-81
Step-by-step explanation:
Step 1: Multiply both sides by x^2-81.
fx3−81fx=x
Step 2: Factor out variable f.
f(x3−81x)=x
Step 3: Divide both sides by x^3-81x.
f(x3−81x)
x3−81x
=x
x3−81x
f=
1
x2−81
The solutions of the inequality is 7.99<x<8.01. I think this solutions means the radius of hole in the bolt or something along that, but I'm not sure.
