Answer:

Step-by-step explanation:

Let B represent the number of books that you buy, and let P represent the number of pens that you buy.

If each book in a store costs $8 and each pen costs $4, it means that the cost of B books and P pens would be expressed as

8B + 4P

If you want to spend exactly $32, then the equation, in standard form, that represents modeling this situation is

8B + 4P = 32

Ahat [919]

Answer:

Option B.

Step-by-step explanation:

It is given that,

Last year the total number of movies = 108

Number of action movies = 15

Based on this data, we need to find a reasonable estimate of the probability that the next movie is an action movie.

So, the required probability is:

\text{Probability}=\dfrac{\text{Number of action movies}}{\text{Total number of movies}}

\text{Probability}=\dfrac{15}{108}

Hence, the correct option is B.

1) What is the solution to x - 5 = 27?
Phoenix [80]
X - 5 = 27

Isolate the x, add 5 to both sides (because of equal sign)

x - 5 = 27
x - 5 (+5) = 27 (+5)
x = 27 + 5
x = 32

x = 32 is your answer

hope this helps

Through: (-5, -5), slope=2/5
kakasveta [241]

For this case we have that by definition, the equation of a line in the slope-intersection form is:

y = mx + b

Where:

m: It is the slope

b: It is the cut point with the y axis

The slope is: m = \frac {2} {5}

Thus, the equation is of the form:

y = \frac {2} {5} x + b

We substitute the given point and find "b":

-5 = \frac {2} {5} (- 5) + b\\-5 = -2 + b\\-5 + 2 = b\\b = -3

Finally, the equation is:

y = \frac {2} {5} x-3

Answer:

y = \frac {2} {5} x-3
