Answer:

58240

Step-by-step explanation:

1425 ------ 45600

1820 ------   x

1425*x = 1425x

45600*1820 = 82992000

1425x = 82992000

82992000/1425 = x

I don’t know the answer to that one can you help me please
dybincka [34]

Answer:

16/45

Step-by-step explanation:

Step 1:  When dividing fractions, use “KFC”.  It means Keep the first fraction, Flip the second one, and  

              Change it to multiplication

-4/20 ÷ -9/16    →    -4/20 ∙ 16/-9

Step 2:  Reduce any fractions if necessary, it makes multiplying them easier and you will have to reduce anyway at the end.  It’s easier arithmetic to reduce at this step.  The first fraction reduces because both the numerator and denominator are divisible by 4.  

-1/5  ∙   16/-9    

Step 3:  Multiply numerators and denominators together to get one fraction

(-16)/(-45)  

Step 4:  Cancel out the negatives, a negative divided by a negative is a positive.  Our final answer is

 

16/45

Factorize a² +3ab - 5ab - 15b².
olga nikolaevna [1]

Answer:

a^2+3\,a\,b-5\,a\,b-15\,b^2=(a-5\,b)\,(a+3\,b)

Step-by-step explanation:

Work via factoring by groups:

!) re arrange the terms as follows:

a^2-5ab+3ab-15b^2

then extract the common factor for the first two terms (a), and separately the common factors for the last two terms (3 b):

a^2-5ab+3ab-15b^2\\a\,(a-5\,b)+3\,b\,(a-5\,b)

Now notice that the binomial factor (a-5 b) is in both expressions, so extract it:

a\,(a-5\,b)+3\,b\,(a-5\,b)\\(a-5\,b)\,(a+3\,b)

which is the final factorization.
