A rectangular auditorium seats 1564 people. The number of seats in each row exceeds the number of rows by 12. Find the number of

Semmy [17]

Basically, it is (R being rows) (S being seats)
R times the amount of rows plus 12 is the amount of seats in each row
RAmnt + 12
You know there are 1564 seats
You don’t know the amount of rows
You know the amount of seats in the row minus 12 is the amount of rows in all
seat per row - 12 = rows
To make it easier start making up the number of rows that are possible
Just do x - 12x over and over with the different numbers
X= 1564/y
For example
If y is 5
312.8 - 12y which would be 252.8

So, let's look at the problem:

|x + 7| < 11

We want to get rid of extra numbers, so lets get rid of that seven my subtracting it! But make sure you do the same thing on both sides!

x < 4

Your answer would be four! Hope I helped! <3

What two numbers multiply to -126 and add up to -65

Airida [17]

Xy = -126
x + y = -65

$xy = -126$
$\frac{xy}{x} = \frac{-126}{x}$
$y = \frac{-126}{x}$

$x + y = -65$
$x + \frac{-126}{x} = -65$
$\frac{x^{2}}{x} + \frac{-126}{x} = -65$
$\frac{x^{2} - 126}{x} = -65$
$-65x = x^{2} - 126$
$0 = x^{2} + 65x - 126$
$x = \frac{-(65) \+ \sqrt{(65)^{2} - 4(1)(-126)}}{2(1)}$
$x = \frac{-65 \± \sqrt{4225 + 504}}{2}$
$x = \frac{-65 \± \sqrt{4729}}{2}$
$x = \frac{-65 \± 68.8}{2}$
$x = \frac{-65 + 68.8}{2}$ $or$ $x = \frac{-65 - 68.8}{2}$
$x = \frac{3.8}{2}$ $or$ $x = \frac{-133.8}{2}$
$x = 1.9$ $or$ $x = -66.9$

x + y = -65
  1.9 + y = -65
- 1.9   - 1.9
y = -66.9
  (x, y) = (1.9, -66.9)

or

  x + y = -65
  -66.9 + y = -65
+ 66.9 + 66.9
y = 1.9
  (x, y) = (-66.9, 1.9)

The two numbers that add up to -65 and can multiply to -126 are the numbers -66.9 and 1.9.
