Answer:
Step-by-step explanation:
Find the least common denominator or LCM of the two denominators:
LCM of 3 and 9 is 9
For the 1st fraction, since 3 × 3 = 9,
2
3
=
2 × 3
3 × 3
=
6
9
Likewise, for the 2nd fraction, since 9 × 1 = 9,
4
9
=
4 × 1
9 × 1
=
4
9
Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction
6
9
>
4
9
or
2
3
>
4
9
10 days for A by 1,000 m = 2 days 5x2=10 And for B it will be 9.75 kilometers on the thrid day because of .75x3=2.25 then put 7,500 meters to 7.5 kilometers then 7.5+2.25=9.75 kilometers on the third day. For C it would be plan B because it would 20 days to get 20 kilometers for A but plan B is two days ahead of A by taking 7.5x3=22.5=20 days 22.5-.75=21.35 21.35-.75=20.60. Hope this helps because it took me a while.
The second one is the correct answer .
Answer:
J 1
--------
x^2 -x
Step-by-step explanation:
x+1
----------
x^3-x
Factor out an x in the denominator
x+1
----------
x(x^2-1)
We can factor the terms in the parentheses because it is a difference of squares
x+1
----------
x(x-1) (x+1)
Canceling the x+1 terms
1
----------
x(x-1)
Distribute in the denominator
1
--------
x^2 -x
Answer:
a) 9 + 3 = 12
b) 5x = (5 x 6 = 30) 30
c) 2x (2 x 3 = 6) = 13
d) 5x (5 x 2 = 10) = 14 + x (10)
