what does (d+3) represent in 4.5(d+3)=45

Answers

Answer 1

Answer:

(d + 3) would be 10

Step-by-step explanation:

Step 1:  Distribute

[tex]4.5(d + 3) = 45[/tex]

[tex](4.5 * d) + (4.5 * 3) = 45[/tex]

[tex]4.5d + 13.5 = 45[/tex]

Step 2:  Subtract 13.5 from both sides

[tex]4.5d + 13.5 - 13.5 = 45 - 13.5[/tex]

[tex]4.5d = 31.5[/tex]

Step 3:  Divide both sides by 4.5

[tex]\frac{4.5d}{4.5} = \frac{31.5}{4.5}[/tex]

[tex]d = 7[/tex]

Step 4:  Determine what (d+3) is

[tex](d + 3)[/tex]

[tex](7 + 3)[/tex]

[tex]10[/tex]

Answer: (d + 3) would be 10

Answer 2

[tex]\huge\text{Hey there!}[/tex]


[tex]\large\boxed{\mathsf{4.5(d + 3) = 45}}\\\\\large\boxed{\mathsf{\rightarrow 4.5(d) + 4.5(3) = 45}}\\\\\large\boxed{\mathsf{\rightarrow 4.5d + 13.5 = 45}}\\\\\large\boxed{\textbf{SUBTRACT 13.5 to BOTH SIDES}}\\\\\large\boxed{\mathsf{4.5d + 13.5 - 13.5 = 45 - 13.5}}\\\\\large\boxed{\textbf{SIMPLIFY IT!}}\\\\\large\boxed{\mathsf{4.5d = 45 - 13.5}}\\\\\large\boxed{\mathsf{4.5d = 31.5}}\\\\\large\boxed{\textbf{DIVIDE 4.5 to BOTH SIDES}}\\\\\large\boxed{\mathsf{\dfrac{4.5d}{4.5}= \dfrac{31.5}{4.5}}}[/tex]

A 2-liter container holds more than a 3,000-milliliter container. True or false?

Answers

To consider whether this statement is true or not

   ⇒ must determine the number of milliliters in a liter

        ⇒ 1 Liter = 1000 milliliter

To compare both containers, lets set both containers in terms of milliliters

Container 1 --> 2 Liter Capacity --> 2000 milliliterContainer 2 --> 3000 milliliter

By looking at the data

  ⇒ the 3000-milliliter container holds more than the2-liter container

Thus, the statement: A 2-liter container holds more than a 3,000-milliliter container

  ⇒ False

Answer: False

Hope that helps!

Answer:

False because 2 liters = 2,000 milliliters. Therefore that is not possible.

The length of the third side is a-2.

Given that:

Perimeter of triangle: 6a + 3

Length of first side: 2(a+3)

Length of second side: 3a -1

Let the length of the third side of the triangle be x.

Then as perimeter of a triangle is sum of lengths of all 3 sides of the triangle, thus we have:

Thus we have length of the third side as a -2.

Answers

Answer:

-4 3/8 thus A. is the answer

Step-by-step explanation:

Simplify the following:

-7/2 - (5/8 + 1/4)

Put 5/8 + 1/4 over the common denominator 8. 5/8 + 1/4 = 5/8 + 2/8:

-7/2 - (5/8 + 2/8)

5/8 + 2/8 = (5 + 2)/8:

-7/2 - ((5 + 2)/8)

5 + 2 = 7:

-7/2 - 7/8

Put -7/2 - 7/8 over the common denominator 8. -7/2 - 7/8 = (4 (-7))/8 - 7/8:

(4 (-7))/8 - 7/8

4 (-7) = -28:

(-28)/8 - 7/8

Answers

Answer:

100% it is  B. 1/2(172 - 58)

Step-by-step explanation:

The expression which gives the measure of ∠ACE in the diagram below is [tex]\frac{1}{2}[/tex] (172° - 58°). So option B is the correct one.

What is Secant Angle Theorem?

Secant angle theorem is a theorem which states that when two secants which intersects the circle at two different points are intersected at a point outside the circle, then the angle formed at the intersection is equal to the half of the measure of the intercepted arcs.

Given a circle with two secants, ABC and EDC, which touches the circle at different points.

They both intersects at point C.

The intercepted arcs are arc AE and arc BD.

Using the Secant Angle theorem, measure of angle ∠ACE is the half of the measure of arc AE and arc BD.

m ∠ACE = [tex]\frac{1}{2}[/tex] (AE - BD) = [tex]\frac{1}{2}[/tex] (172° - 58°)

Hence the required expression is 1/2 (172° - 58°).

y = - (1/5)x + 2

when the function is in slope intercept form, (m) is the rate of change or the slope.

Givens

right angle

The right angle's supplement (which is also 90degrees) of (6x + 5y)

Solution

10y = 90               See remarks for reason. Divide by 10

10y/10 =90/10

y = 9

6x + 5y =90

6x + 5*9 = 90      Combine

6x + 45 = 90        Subtract 45 from 90

6x = 90 - 45         Combine

step-by-step answer please

Answers

Step-by-step explanation:

Step I: [Take only first 5 digits] A five digit number divisible by 5 can only end with '5'(0 is not allowed)

=> Middle digit is 5. Number is _ _ _ _ 5 _ _ _ _

Step II: All even digits should be even. because they'll be divided by an even number.

Step III: [Take only first 8 digits]An eight digit number with 6th digit as even number, last 2 digit can have only 4 combinations, . These are 96, 16, 72, 32. Number will be as follows:

(EDIT: Considering that it is divisible by 8 and 7th digit is odd)

_ _ _ _ 5 _ 1 6 _

_ _ _ _ 5 _ 9 6 _

_ _ _ _ 5 _ 7 2 _

_ _ _ _ 5 _ 3 2 _

Step IV: [Take only first 4 digits]A four digit number divisible by four ends only with 2 or 6. Keeping in mind that these number don't repeat only 4 Combinations are possible:

(EDIT: Using the fact that 3rd digit is odd and is divisible by 4)

_ _ _ 2 5 _ 1 6 _

_ _ _ 2 5 _ 9 6 _

_ _ _ 6 5 _ 7 2 _

_ _ _ 6 5 _ 3 2 _

Step V: [Take only first 6 digits]For a number to be divisible by 6; 6th number should be even and last three digit should add up to make a multiple of 3. Only 4 Combinations possible

_ _ _ 2 5 8 1 6 _

_ _ _ 2 5 8 9 6 _

_ _ _ 6 5 4 7 2 _

_ _ _ 6 5 4 3 2 _

Step VI: Now only one even number is remaining for occupying 2nd place in each of the above combination. For example in Ist case: 4 is the only remaining even number to be consumed. The combination will go as follows:

_ 4 _ 2 5 8 1 6 _

_ 4 _ 2 5 8 9 6 _

_ 8 _ 6 5 4 7 2 _

_ 8 _ 6 5 4 3 2 _

Step VII: Total 10 combinations remain:

1 4 9 2 5 8 1 6 _

9 4 1 2 5 8 9 6 _

3 8 1 6 5 4 7 2 _

1 8 3 6 5 4 3 2 _

3 8 1 6 5 4 7 2 _

1 8 3 6 5 4 3 6 _

1 8 9 6 5 4 7 2 _

9 8 1 6 5 4 3 2 _

1 8 9 6 5 4 7 2 _

9 8 1 6 5 4 3 2 _

Step VIII: Taking only first 7 digits of all of the above numbers. Only 3816547 is divisible by Seven

Complete number 381654729 is divisible by 9.

I am sure only 381654729 thus satisfies the answer.

Answers

Answer:

[tex]y-6=\frac{3}{2} (x+6)[/tex]

Step-by-step explanation:

Hi there!

We are given a point (-6, 6) and a slope of [tex]\frac{3}{2}[/tex]

We want to write the equation of the line that contains this point and slope in point-slope form

Point-slope form is written as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point

As we are already given everything we need, we can simply substitute the values into the formula

Starting with the slope, substitute 3/2 as m into the equation:

[tex]y-y_1=\frac{3}{2} (x-x_1)[/tex]

Now substitute -6 as [tex]x_1[/tex] and 6 as [tex]y_1[/tex]

[tex]y-6=\frac{3}{2} (x--6)[/tex]

Simplify:

[tex]y-6=\frac{3}{2} (x+6)[/tex]

The Danxia Landforms, named after Mount Danxia in Guangdong province, are breathtaking landforms that are unique to China. They were formed over a period of around 24 million years when rivers deposited red sandstone and other minerals. But lets learn more about this. The layers of this natural occurrence are a variety of colors, including blue, red, purple, and many others. There are also various kinds of landscapes. There are steep cliffs, waterfalls, mountains, and other natural features. There are spectacular sights and unusual mountains, such as tall, rounded ones. Danxia in Zhangye was formed by the erosion of red sandstone, resulting in isolated peaks and steep stratified outcrops. Its extraordinary geological formation, along with long-term desert conditions, freeze-thaw peeling, wind and water erosion, and other causes, resulted in its current appearance. The landforms now have a wonderful array of shades! The colorful mountains, though, are not the only feature to see there! Let's find out what else is out there. Hills and mountains of various shapes and sizes can be found at the Danxia Landforms. This natural phenomenon has a variety of sights to see, ranging from small orange hills to massive rainbow mountains. At the Binggou Danxia landform, for example, there are sandstone and rock formations in numerous shades of orange. Not to mention Mt. Danxia, a massive curved mountain!There are several geological occurrences in the Danxia Landforms, ranging from rainbow mountains to orange rock formations.
