-3x + -15 = 12
x = __

Answers

Answer 1

Answer:

x=9

Step-by-step explanation:

alright so first we eliminate the -15 and to do that we add 15 on both sides:

-3x-15+15=12+15

-3x=27

Now we divide 3 on both sides to make the equation equal to x

[tex] \frac{-3x}{-3} = \frac{27}{-3} [/tex]

x=9

And that's your answer, you're welcome :)

The graph shown has a slope of -4 (the line goes up 4 units for every 1 unit traveled to the left)

The y-intercept (where the line crosses the y axis) is -3

Slope-intercept form is y=mx+b

(m=slope)

(b= y-intercept)

Therefore, your answer would be y=-4x-3

The ratio of cats to dogs is 3 : 7.
12 dogs escaped and the ratio is now 3 : 4.
Work out how many animals there were at the beginning.

Answers

Given:

The ratio of cats to dogs is 3:7.

12 dogs escaped and the ratio is now 3 : 4.

To find:

The total number of animal at the beginning.

Solution:

Let the number of cats and dogs at the beginning are 3x and 7x respectively.

12 dogs escaped. So, the remaining number of dogs is (7x-12).

New ratio of cats and dogs is 3:4.

[tex]\dfrac{3x}{7x-12}=\dfrac{3}{4}[/tex]

[tex]4(3x)=3(7x-12)[/tex]

[tex]12x=21x-36[/tex]

[tex]12x-21x=-36[/tex]

[tex]-9x=-36[/tex]

Divide both sides by -9.

[tex]\dfrac{-9x}{-9}=\dfrac{-36}{-9}[/tex]

[tex]x=4[/tex]

Now, the total number of animals at the beginning is

[tex]Total=3x+7x[/tex]

[tex]Total=10x[/tex]

[tex]Total=10(4)[/tex]

[tex]Total=40[/tex]

Therefore, the total number of animals at the beginning is 40.

Answer: 56 times

Step-by-step explanation:

If his ratio of goals to misses is

6:7

then we must find out how many times he missed seeing he scored 48

so

48:?

to solve find out if 6 goes into 48 and it does 8 times so multiply both sides by 8 to get the new ratio

6*8:7*8

48:56

So the new ratio is 48:56 which also means he missed 56 shots

Answer:

  9.9

Step-by-step explanation:

The applicable geometric mean rule tells you ...

  y = √(9(9+2)) = √99

  y ≈ 9.9

__

Additional comment

In this geometry, the right triangles are similar. Ratios of corresponding sides are equal.

  hypotenuse/long side = y/9 = (9+2)/y

  y^2 = (9)(11)

  y = √99 . . . . as above

The long leg is the geometric mean of the (adjacent) long segment and the full hypotenuse.

In each of the following graphs, the two given polygons are similar. Write precisely a single dilation (coordinates of center and coefficient) by which the image (labeled with primed letters) was obtained. Will Give Brainiest!!!!!

Answers

Answer:

Center: (0,0)   coefficient: [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

The side of the smaller polygon is 1/3 the size of the larger one, and that is why the coefficient is 1/3.

Polygon MNPQ was dilated by a scale factor of 1/3 and center of dilation (0, 0) to create M'N'P'Q'.

What is dilation?

Dilation is the increase or decrease in the size of a figure by a scale factor of k, thereby creating an image.

From the diagram:

Scale factor = N'P' / NP = 2/6 = 1/3

Center = (0, 0)

Polygon MNPQ was dilated by a scale factor of 1/3 and center of dilation (0, 0) to create M'N'P'Q'.
