Question 193673: How many yards of material from a 24-yard length of cloth remain after 3 each 3 1/2 yards long, and 5 pieces each 2 1/4 yards long are removed?
sol:Total length of the cloth=24 yards
the length of the cloth after removing 3 pieces of length 31/2 yards=24-(3*3.5)
(i.e 1/2=0.5,3 1/2=3+0.5=3.5)
=24-10.5
=24.0-10.5=13.5
now the length of the cloth=13.5 yards
again the length of the cloth after removing 5 pieces of length 2 1/4 yards=13.5-(5*2.25)
(i.e;1/4=0.25,2 1/4=2+.25=2.25)
=13.5-11.25
=13.50-11.25
=2.25 yards
the length of the remaining cloth=2.25 yard

Question 197816: 2 5/2- 2 3/2=
I believe the answer should be one and so does your site, but on a college level entrance exam it is telling me the answer is 2 3/2. It is a fraction problem. I basically just
9/2-7/2
after converting them
2/2=1?
Please any help or suggestions would be appreciated.

Question 199258: Could someone explain how I should solve these three problems;
Use the synthetic substitution to find the value of f(-2) for f(x)=x^3-3x^2-x-9.
Use the Factor Theorem to determine whether (x-3) is a factor of f(x)=x^4+12x^3+6x+27.

Question 199482: I guess algebra just really isnt my strongest point, could someone help me here,
I totally didnt understand this one; If y varies directly as x and inversely as z^2, and y= 3 when x=2 and z=4, what is the value of x when y=9 and z=4?

Question 199485: I tried this problem by myself but not sure if I got it right, and have the feeling that I dont;
If x varies as y and x=2 when y=8, find x when y=17;
so y=k/x 8=k/2 k=16 y=16/x y=17 so 17=16/x x=16/17
I know I am a mess when it comes to algebra.....
