Answer:

  9

Step-by-step explanation:

The first sentence of the problem can be interpreted two ways. The way that makes the second sentence work out correctly is ...

  'a larger number is 5 less than 3 times a smaller number'

Using x for the smaller number, the two equations that can be written are ...

  • 3x -y = 5
  • x +4y = 97

Adding 4 times the first equation to the second, we get ...

  4(3x -y) + (x +4y) = 4(5) +(97)

  13x = 117 . . . . . simplify

  x = 9 . . . . . . . . divide by 13

The smaller number is 9.

3x^2+17x-9/x+4 what is the quotient
zvonat [6]

Answer:

The quotient of given expression is (3x+5).

Step-by-step explanation:

The given expression is

\frac{3x^2+17x-9}{x+4}

The coefficients of dividend are 3,17 and -9.

Use synthetic division to divide 3x^2+17x-9 and x+4.

The bottom row represents the coefficient of quotient and remainder.

The given expression can be written as

\frac{3x^2+17x-9}{x+4}=3x+5-\frac{29}{x+4}

Therefore the quotient of given expression is (3x+5).

How do you divide with the median
Savatey [412]
When doing the median you first place the numbers for least to greatest, then you cross off each side until you get your middle number. If the is two middle numbers then you add the two middle numbers the divide by two. Example:
What is the median for the numbers 12,24,35,2,67,80,45,and 95? First put the numbers from least to greatest. 2,12,24,35,45,67,80,95. ( REMEMBER that if you have an even number of numbers than your going to have two medians, if you have an odd number of numbers than you will have one median!) the middle numbers are 35 and 45, so you add 45+35 which equals 80. 80 divided by 2 is 40. Hope my example helped you understand this! :)
