There is a total of 5 numbers so what you need to do is take 100 and divide it by 5 you'll get 20 chances per number. 100/5=20

Now take 20 and times the amount of odd numbers you have 20x3=60.

You can expect to land on an odd number 60 out of 100 spins.

We would expect the spinner to spin an odd number 67 times. Hope this helps! :)

A new computer has a model number, a part number, and a serial number. The model number is assigned by the manufacturer to ident
kumpel [21]
<span>(serial number, model number)

That's a function mapping each serial number to its model number.

 (part number, serial number)

That's not a function; the same part number is in computers with different serial numbers

</span><span> (model number, part number)
</span><span>
That one's a bit confusing.  Normally a given model would have more than one part number inside so this isn't a function.  But here the description says there's only one part number for each model, so that would be a function.

(model number, serial number)

Not a function, more than one serial number for a given model number.

1.
3n + 5 = 6
3n = 6 - 5
3n = 1
n = 1/3

2.
4 + 5x = 1
5x = 1 - 4
5x = -3
x = -3/5

3.
4y - 15 = -10
4y = -10 + 15
4y = 5
y = 5/4

4.
3 - 4d = 13
-4d = 13 - 3
-4d = 10
d = -10/4
d = -5/2

5.
8 = 9x - 7
8 + 7 = 9x
15 = 9x
15/9 = x
5/3 = x

hope this helped, God bless!

a charitable organization in Lanberry is hosting a black tie benefit. Yesterday, the organization sold 55 regular tickets and 49
jenyasd209 [6]

Answer:

  • regular: $67
  • VIP: $122

Step-by-step explanation:

Let r and v represent the costs of a regular and VIP ticket, respectively. The two sales can be represented by ...

  55r +49v = 9663

  79r +84v = 15541

We can subtract 7 times the second equation from 12 times the first to eliminate the v terms.

  12(55r +49v) -7(79r +84v) = 12(9663) -7(15541)

  660r +588v -553r -588v = 115,956 -108,787 . . . . . eliminate parentheses

  107r = 7169 . . . . . . . simplify

  r = 67 . . . . . . . . . . . divide by 107

Using this value in the first equation, we have ...

  55(67) +49v = 9663

  v = 5978/49 . . . . . . . . . subtract 3685, divide by 49

  v = 122

A regular ticket costs $67; a VIP ticket costs $122.

<em>Additional comment</em>

When using "elimination" to solve a system of equations, you're looking for coefficients of the same variable that are related by small factors. Preferably, one coefficient is the same as, or a small multiple of, the other. Here, 55 and 79 (the coefficients of x) are not related by an integer, or a couple of small integers. On the other hand, the y-coefficients 49 and 84 have a common factor of 7, and are in the ratio 7:12, a pair of small numbers. This is why we chose to eliminate the y-variable.

The x-variable could be eliminated using 55 and -79 as multipliers of the equations. This results in larger numbers, and more chance for error. (Errors tend to creep in when computing or copying large numbers.)

Of course, any of several machine methods could be used to solve these equations, including graphing and matrix-solving functions. Here, we tried to honor the requirement to solve by elimination.

The sum of nine and twice a number is 5353. find the number.
Nadya [2.5K]
Equation: 9+2x=5,353
               -9        -    9
                     2x=5,344
then divide both sides by 2 

                    x=2,672
