Answer:
3x^2-4x+20/x^2-5x .
Step-by-step explanation:
The given rational expression is:
3x/x-5 - 4/x
Hence to find the difference of the rational numbers we have to take the L.C.M of the denominators:
Thus the L.C.M of x-5 and x is (x-5)(x) and then solve for the numerator:
x(3x) - 4(x-5)/(x-5)(x)
Now solve the numerator and denominator:
3x^2-4x+20/x^2-5x
Thus the answer is 3x^2-4x+20/x^2-5x ....
If you were to borrow $4 from one person and you borrow $10 more from another person. How much do you owe altogether?
Z=5.714285714285714 because you subtract 0.3z from 0.02z which = 0.28z and then subtract.2 from 1.8 which is 1.6. So then divide 1.6 by 0.28 to find z.
Answer:
about 12000 but real answer is 12224
Step-by-step explanation:
Some operators are missing.
If the right equations are y = x^2 -6x +8 and 2y + x =4
This is the solution
2y + x = 4
2y = -x +4
y = -x/2 + 2
y = x^2 -6x + 8 = -x/2 + 2
2x^2 - 12x + 16 = -x + 4
2x^2 -11x +12 = 0
Factor
(x-4)(2x-3)=0
x= 4 and x =3/2
y = -x/2 +2
y = -4/2 + 2 = 0
y = - (3/2)/2 + 2 = -3/4 + 2 = 5/4
Answer (4,0) and (3/2, 5/4)
