Answer:

$28 3/4

Step-by-step explanation:

One way of doing this is to sum up the increases and the decreases of the price, separately.  One then adds the increases to the beginning price ($33 3/8) and subtracts the decreases from this sum:

$33 3/8 + ($4 1/4) - ($8 7/8),      where $33 3/8 is the beginning price,

                                                    $4 1/4 is the sum of the price increases

                                                     for the day, and $8 7/8 is the sum of the

                                                     price decreases for the day.

Then we have:

$33 3/8 + $4 2/8 - $ 8 7/8

Here we need sum up the beginning price and the price increase for the day first:

$33 3/8 + $4 2/8 = $37 5/8

We cannot subtract $8 7/8 from $37 5/8 without borrowing.  Borrowing, we get:

$36 13/8

and from this we subtract $8 7/8:

$36 13/8

- $  8 7/8

----------------

 $28 6/8

This can be reduced to $28 3/4.   This was the closing price.

sasho [114]

Answer:

$51.33

Step-by-step explanation:

Everything is off 65% so that means that $15.40 if 35% of the original price(100%-65%)

Set up Equation:

\frac{15.40}{x} = \frac{30}{100}

Simplify:

\frac{15.40}{x} =\frac{3}{10}

Multiply the first numerator by the last denominator and the first denominator by the last numerator

3x=154

Divide 3 by both sides:

x= 51.33

Matthew and Anthony each have a video game collection. The number of video games in Matthew’s collection can be represented by x
Blababa [14]

The number of video games in Matthew’s collection is 12

To solve the problem, we need to know what simultaneous equations are

<h3>What are simultaneous equations?</h3>

These are a pair of equations which contain two variables.

Now, let

  • x = number of video games in Matthew's collection and
  • y = number of video games in Anthony's collection.

Given that the number of video games in Anthony’s collection is 5 times the number in Matthew’s collection, we have that y = 5x (1)

Also, the total number of video games in both collections is 72.

So, x + y = 72 (2)

Substituting equation (1) into (2), we have

x + 5x = 72

6x = 72

x = 72/6

x = 12

So,  the number of video games in Matthew’s collection is 12

(x + 2)(x + 3)(x + 4) can be written in the form x + ax² + bx + c
ELEN [110]

Answer:

a=9, b=26, c=24

Step-by-step explanation:

Let's expand the expression bit by bit.

(x+2)(x+3)=(x)(x)+(x)(3)+(2)(x)+(2)(3)=x^2+5x+6 by FOIL.

We have that (x^2+5x+6)(x+4)=x(x^2+5x+6)+4(x^2+5x+6)=x^3+5x^2+6x+4x^2+20x+24=x^3+9x^2+26x+24.

So, the answer is \boxed{a=9, b=26, c=24}
