Answer:
7. (4x +10)/(x^3 +3x^2 -16x -48)
9. -320/93
Step-by-step explanation:
7. As with adding any fractions, first you find a common denominator. When the fractions are rational expressions, it often helps to factor the denominators.
6/(x^2 -16) -2/(x^2 -x -12) = 6/((x -4)(x +4)) -2/((x -4)(x +3))
= (6(x +3) -2(x +4))/((x -4)(x +3)(x +4)) . . . . . using a common denominator
= (6x +18 -2x -8)/((x -4)(x +3)(x +4))
= (4x +10)/((x^2 -16)(x +3))
= (4x +10)/(x^3 +3x^2 -16x -48)
_____
9. First you simplify the denominator:
2/25 -5/16 = (2·16 -5·25)/(25·16) = -93/400
Then you perform the division. This can be done by multiplying by the inverse of the denominator.
(4/5)/(2/5 -5/16) = (4/5)·(-400/93) = -320/93
Answer:
About 48%
Step-by-step explanation:
divide 30% by 62% and that would be approximately 0.48 or 48%
Answer:
7/6
It's 7/6 because 6/6 make up a whole which is the 1 in 1 1/6
then there is that left over 1/6 to make it 7/6
Answer:
C. 5 goes into 100 twenty times, and 1 times 20 is 20
Step-by-step explanation:
Since, we know that when we multiply both numerator and denominator of a fraction by a same number then we obtain an equivalent fraction,
Here, the given fraction,

By the above statement,

Now,


Hence,

Option C is correct.
