The correct answer is A, because all the numbers multiplied together equal 54 and all the numbers are prime
Hope this helps!

likoan [24]

<span>Open and closed circles are used to mark the end points of intervals. If the circle is open, it means the end point is NOT included in the interval, but if the circle is closed, it means the end point is included. Consider the interval . In this interval, the low endpoint, the 3, is not included because you have a 'less than' sign. The high endpoint, the 6, is included because you have a 'less than or equal' sign. It is the presence or absence of the 'or equal' part that determines whether the circle is closed or open. The interval would be marked on the number line with an open circle at 3, a closed circle at 6, and a heavy line connecting the two.

(x+2)(x-3)<br><br> (x+2)(x-3)

gregori [183]

Answer:

x² - x - 6

Step-by-step explanation:

Given

(x + 2)(x - 3)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x - 3) + 2(x - 3) ← distribute parenthesis

= x² - 3x + 2x - 6 ← collect like terms

= x² - x - 6

Lucy had math and reading homework tonight. Lucy can solve each math problem in 5 minutes and she can read each page in 2.5 minu

drek231 [11]

Answer:

$x=18,y=6$ , graph is there for reference.

Step-by-step explanation:

Given,

$x$ is the number of math problem Lucy solved.

$y$ is the number of pages she read.

She can do each math problem in $5$ minutes, therefore she can solve $x$ number of questions into $5 \times x=5x$ minutes.

She can read each page in $2.5$ minutes, therefore she can read $y$ pages in 2.5y minutes.

As per given detail,

$5x+2.5y=105$ equation 1.

And,

It is given that number of math problems Lucy solved is 3 times the number of pages she read.

$x=3y$ equation 2.

We need to find $x$ and $y$ intercept of each of the equation to graph them.

For $x-intercept$ put y=0

We will get $x=\frac{105}{5} =21$

Thus the point is $(21,0)$

Let us find $y-intercept$ by assuming $x=0$

we get $y=\frac{105}{2.5} =42$

Thus the point is $(42,0)$

Join these two points.

Similarly considering the other equation $x=3y$

Here x-intercept would be at $y=0$

We will get $x=0$

Thus the point is $(0,0)$

Let us assume on more point, say $x=30$ , we get $y=10$

Thus the point is $(30,10)$

Join these two points.

We will get a point of intersection at $(18,6)$

Thus $x=18$ and $y=6$

If x/y=5/8 state whether the following is true or false

Valentin [98]

Answer:

they are both true

Step-by-step explanation:

they are both true because of proportionalities

5/8

5x2=10

8x2=16

therefore 5/8=10/16

the second one is also true because they want you to multiply y by 2

4x2=8

therefore

5/8=5/4x2
