-9x/x-x^2 how do you simplify?

Mathematics

Usimov [2.4K]3 years ago

I believe you have omitted the parenthesis in the denominator, if so the term is:

-9x/(x-x²)

The denominator can be written after factorizing it x(1-x)

==> -9x/[x(1-x)] , you cancel x ==> -9/(1-x) or 9/(x-1)

There are 180 students participating in after school activities. Of those students 40% are boys . How many girls are participati
Nezavi [6.7K]

i dont want to assume all the other people participating in after school activities are girls but if they are, the answer is 108.

180 = 100%

x = 40%

the information above shows that 60% are girls

60% of 180 = 108 or 0.60 x 180 = 108

the answer is 108

hope this is helpful!

Sweety’s mother is 12 years more than twice Sweety’s age. After 8 years, she will be 20 years less than three times Sweety’s age
poizon [28]

Answer:

Sweety's age = 16 years and  Sweety’s mother’s age = 44 years

Step-by-step explanation:

Let Sweety's age is x.

Sweety’s mother age = 12+2x

After 8 years,

Sweety's age = x+8

Sweety’s mother age = 12+2x+8

Since Mother's age will be 20 years less than three times my age.

2x+20 = 3(x+8)-20

2x+20=3x+24-20

2x+20=3x+4

Taking like terms together,

20-4=3x-2x

x = 16

Sweety's age = 16 years

Sweety’s mother’s age = 12+2x

= 12+2(16)

= 12 + 32

= 44 years

Hence, Sweety’s age and Sweety’s mother’s age is 16 years and 44 years respectively.
