Answer: 32

Step-by-step explanation:

All you have to do is is multiply 8 by the numbers in the parentheses. So you multiply 8 by 3, which equals 24. Then multiply 8 by 4, which is 32. Hope this helps! :)

Your school is planning a field trip to a history museum. They are going to rent a large bus for $450. The cost of the ticket to
Sunny_sXe [5.5K]

Answer:

19

Step-by-step explanation:

To write an equation for the first situation, you need to determine which factors can be changed.  The bus will not change since you can have multiple people in one.  The ticket to the museum is per person.  This will change depending on how many people there are.

450 + 15.75x

For the second equation, you need to find how many people can go for it the cost to be equal to $40 per person.  Set the equation equal to $40 per person and solve.

450 + 15.75x = 40x

450 = 24.25x

x = 18.56

Round up to 19 since you can't 0.56 of a person.

Need help with this please!!!
BARSIC [14]
I don't like dividing polynomials so I'm going to set x=1 and try them out.

(1-2-14+3)/4 = -3

Of the choices, only D gives -3 when x=1

~~~~~~~~~~~~~~~~~~~~~~

That's as much test-taking as math.  If we were to divide


             x^2 - 5x + 1
          -------------------------------
x + 3 |   x^3 - 2x^2 - 14x + 3
             x^3 + 3x^2
                      -5x^2 - 14x
                       5x^2 + 15x
                                      x + 3 
                                      x + 3

More work, still choice D

Sarah wants to paint three walls in her family room. Two walls are 18 feet long by 10 feet
Brrunno [24]

Answer:

The total area is 444 ft².

Step-by-step explanation:

First you multiply 18 by 10 for one of the walls you get 180*2 since you have two walls with the same dimension. Next you do 12*7 to get 84. Last you would add 84 to 360 and get 444 ft²

<em>Assume that the given parameter is: 4</em>

Required

The multiplicative inverse

Let a number be x, and the multiplicative inverse be y. The relationship between them is:

y * x = 1

Make y the subject

y = \frac{1}{x}

So;; for the assumed given parameter.

The multiplicative inverse is:

y = \frac{1}{4}
