Answer:

Step-by-step explanation:

To find the value of x, isolate it on one side of the equation.

3/4x+9=3

First, subtract by 9 from both sides.

3/4x+9-9=3-9

Solve.

3-9=-6

Rewrite the problem down.

3/4x=-6

Multiply by 4 from both sides.

4*3/4x=4(-6)

Solve.

3x=-24

Then, you divide by 3 from both sides.

3x/3=-24/3

Solve.

Divide these numbers goes from left to right.

-24/3=-8

x=-8

Variables and negative signs should appear in the answer.

I hope this helps you! Let me know if my answer is wrong or not.

Answer:

x = -8

Step-by-step explanation:

Subtract 9 both sides:

⇒ 3/4x + 9 = 3

⇒ 3/4x + 9 - 9 = 3 - 9

Simplify the L.H.S and the R.H.S:

⇒ 3/4x = -6

Use cross multiplication:

⇒ 3x/4 = -6

⇒ 3x = -6 × 4

Simplify the R.H.S:

⇒ 3x = -6 × 4

⇒ 3x = -24

Divide 3 both sides:

⇒ 3x/3 = -24/3

⇒ x = -8

How to solve:

     By finding the perimeter of the fence in feet, we can check that value against the 4 proportion options listed in the problem. Whichever is true will be the correct answer.

Perimeter - in feet

Where P is perimeter in miles, x is perimeter in feet, w is width in miles, and L is length in miles.

Set up equation                                                     P = 2w + 2L

Substitute                                                               P = 2(1/8) + 2(1/4)

Simplify                                                                   P = 2/8 + 2/4

Common denominator                                          P = 1/4 + 2/4

Simplify                                                                   P = 3/4 mi.

Translate                                                                x = (3/4)*5280

Simplify                                                                   x = 3960 ft.

For the following: Where m represents the mile unit, f represents the foot unit, and x represents the number of feet of fencing.

First option

Set up equation                                            (3/4)m/x = m/5280f        

Equal variables                                         16[(3/4)m/x) = 12[m/5280f]

Simplify                                                             12m/16x = 12m/63360f

Remove miles                                                          16x = 63360f

Isolate x variable                                                    /16     /16

Solution                                                                       x = 3960 ft.

Second Option

Set up equation                                             (3/8)m/x = m/5280f

Equal variables                                         64[(3/8)m/x] = 24[m/5280f]

Simplify                                                              24m/64x = 24m/126720f

Remove miles                                                            64x = 126720f

Isolate x variable                                                      /64     /64

Solution                                                                          x = 1980 ft.

Third Option

Set up equation                                               x/(3/4)f = m/5280f

Equal variables                                      7040[x/(3/4)f] = m/5280f

Simplify                                                   7040x/5280f = m/5280f

Remove feet                                           7040x = m

Translate                                                 7040x = 5280f

Isolate x variable                                   /7040     /7040

Solution                                                           x = (3/4)f

Fourth Option

Set up equation                                             x/(3/8)f = m/5280f

Equal variables                                  14080[x/(3/8)f] = m/5280f

Simplify                                               14080x/5280f = m/5280f

Remove feet                                        14080x = m

Translate                                              14080x = 5280f

Isolate x variable                                /14080     /14080

Solution                                                         x = 3/8f

Check:

If the perimeter of the fence, in feet, is the first option, then when

x = 3960, the number of miles and feet should be equal. Let's test this.

(3/4)m/x = 1

(3/4)m/3960f = 1

(3/4)(5280f)/3960f = 1

3960f/3960f = 1

1 = 1

Therefore, option 1 is correct.

Answer:

5

Step-by-step explanation:

[tex]12 - 2(3h) = - 18 \\ 12 - 6h = - 18 \\ - 6h = - 18 - 12 \\ - 6h = - 30 \\ h = \frac{ - 30}{ - 6} \\ h = 5[/tex]

Answer:

H=5

Step-by-step explanation:

Simplifying the equation

We multiply 2(3H) =6H, so the equation is now 12-6H=-18

Isolating the Variables

Then, we subtract 12 from both sides, giving us -6H = -30

Finding H

Finally, we divide both sides by -6, so H= 5

Answer:

Hi!

So, for question 4, when you divide it by two, you can split it horizontally to make it 6 squares instead of 3 rectangles from the model of the 1/3, leaving 2 shaded squares and 4 unshaded squares. And since you're dividing it by 2, you only use 1 of the shaded squares.

For question 5, I made the one-half horizontal instead of vertical so you can easily overlap the 2 models when you multiply them. Similar to question 4, the model becomes 6 squares and the 2 models overlap on one square.

Hope this helps! :)

The volume of the prism shaped fish tank is: 408 in.³.

Volume of prism = base area × height of prism.

The fish tank is a prism having a height of 8 inches. To find its volume, find the base area, which is the area of the composite figrue given.

Thus:

Base area = area of rectangle + area of triangle = (length × width) + (1/2(base × height).

Given:

Therefore:

Base area = (7 × 6) + 1/2(3 × 6)

Base area = 51 in.²

Volume of the prism shaped fish tank = 51 × 8 = 408 in.³.

I'm not sure what you mean by those steps mean but here is how I would answer using the elimination method:

3x - 12y = 5

minus (each term separately: 3x - 3x, -12y - -y, and 5 - 9)

3x - y = 9

This eliminates the 3x and = -11y = -4

You can then simplify from there and get y = 4/11

What we know:

How to solve:

  We need to find the probability of drawing one of 3 diamond face cards, which gives us all of the information we need. Using division, we can create a 'x amount of diamond face cards/y amount of total cards' probability.

Probability of a diamond  face card

Where P is the probability of drawing that card, x is the number of diamond face cards, and y is the total amount of cards.

Set up equation                                                     P = x/y

Substitute                                                               P = (3)/(52)

Answer: 3/52 (~5.77%)

Because there are 3 diamond face cards in the deck, the chance of drawing one is {3 cards out of 52 total}, which is 3/52.

The chance of drawing ANY face card is {(3 per suit, 4 suits=) 12 cards out of 52 total} 12/52 (~23.08%),

The chance of drawing ANY diamond card is {1 suit out of 4 suits} 1/4 (25%)

Answer:

B. 150 ft

Step-by-step explanation:

Perimeter of a rectangle = 2(Length) + 2(Width)

Here, we are given the perimeter and width and we want to find the length

We can do so by plugging in what we are given into the perimeter formula and solving for length.

Perimeter = 2(Length) + 2(Width)

Perimeter = 450 and Width = 75

450 = 2(Length) + 2(75)

We now solve for length

==> simplify multiplication 2(75) = 150

450 = 2(Length) + 150

==> subtract 150 from both sides

300 = 2(Length)

==> divide both sides by 2

150 = Length

And we are done!

The answer is B 150ft
