Answer:

The equation after applying the Distributive property:

6 = 9x + 27

The equation solved:

x = -2.33333333

Step-by-step explanation:

The distributive property means that you will multiply the items inside of the parenthesis by the number right out side, in this case (x + 3) by 9.

9 * x = 9x

9 * 3 = 27

our new equation will look like:

6 = 9x + 27

now we will be able to solve!

let’s start by subtracting 27 from both sides.

27 - 27 = 0

6 - 27 = -21

9x = -21

divide both sides by 9.

9x/9 = x

-21/9 = -2.33333333

x = -2.33333333

The value of x from the given equation is x=-7/3.

The given equation is 6=9(x+3).

The distributive property states that an expression which is given in form of A (B + C) can be solved as A × (B + C) = AB + AC.

Using distributive property

6=9(x+3)

⇒ 6=9x+27

⇒ 9x=-21

⇒ x=-21/9

⇒ x=-7/3

Therefore, the value of x from the given equation is x=-7/3.

Answer: 8 and 21

Step-by-step explanation:

Given :

One afternoon she dove -7.8 feet.

Her next two dives were each 2 1/8 feet deeper than the dive before it.

To Find :

The depths of her second and third dives.

Solution :

Depth of her second dive,

[tex]d_2=-(7.8+2\dfrac{1}{8})\\\\d_2=-(7.8 + \dfrac{17}{8})\\\\d_2 = -9.925\ feet[/tex]

Depth of her third dive,

[tex]d_3 = -(7.8 + 2\times 2\dfrac{1}{8})\\\\d_3 = 12.05\ feet[/tex]

Therefore, the depths of her second and third dives is -9.925 feet and -12.05 feet.

Hence, this is the required solution.

Answer:

I'm sorry I don't know the equation, but she walks 3 mph.

Step-by-step explanation:

We know that the answer is asking for speed, which needs both distance and time, so we also need both. Which is where the 9 mph is used. 9 mph means its a difference. b means biking mph, w means walking mph, sooo ----->>> b=w+9, and the difference in the 1st equation is 36, which means the first equation is 4 times larger than the b=w+9, so she walked 48 miles, as well as walked 12 miles in 4 hours. Divide then distances by 4, and you get 12 miles and 3 miles in one hour. Or 12 mph & 3 mph, which fits into 12=3+9. So she walks 3 miles per hour.

Step-by-step explanation:

Answer: DE is 15 and AB is 6

Step-by-step explanation:

Okay, so when two shapes are similar, that means they are proportional. Look at the sides. Notice how the lengths of each side on the larger triangle are all multiples of the lengths of the smaller triangle (side CE, for example, is 24, and AC is 8 since 24 is 3 times larger than 8, you know that particular side was dilated by 3x).

Since these are similar, but not congruent, you know that the dilation was applied to the entire shape equally. In other words, each side is dilated by 3 or is 300% larger.

So, to find DE, just multiply the corresponding side, BC, by 300%.

5*300% (or just 5*3) is 15. So, DE is 15cm long. Make sense?

For AB, you know the scale factor is 3, so you have to figure what number times 3 will get you 18. Because 6*3 is 18, you know AB has to be 6.

Answer:

The stack will be 4.54 feet tall

Step-by-step explanation:

Firstly, we want to write the decimal expression for 2 3/11

That will be 2 + 0.2727

To 2 decimal place, that will be 2.27

Staking the two boxes means we are placing one on the other

So the height of the stack will be 2.27 + 2.27 = 4.54 feet

Answer:

5feet by 4/3feet

Step-by-step explanation:

The scale use for a model of kitchen is 1/4 in = 1/2 ft In the model, the kitchen measures 2 1/2 by 2 /3 in. What are actual dimensions of the kitchen.

From the question, we were given the conversation rate of 1/4 in = 1/2 ft In the model,

To get actual dimensions of the kitchen if the kitchen measures 2 1/2 by 2 3 in. Then

✓Let us convert 2 1/2in to feet first= 5/2in as improper fraction.

If 1/4 in = 1/2 ft

5/2in = x ft

Then cross multiply, we have

(5/2×1/2)= 1/4 × X

5/4 = 1/4X

Make X subject of the formula

X= (5/4)/(1/4)

X=5ft.

✓Let us convert 2/3in to feet

If 1/4 in = 1/2 ft

2/3in = x ft

Then cross multiply, we have

1/4×X=2/3×1/2

X=(2/3×1/2)/(1/4)

X=4/3feet

Therefore, the actual dimensions of the kitchen is 5feet by 4/3feet
