If 7/9x - 4/9x = 1/4 +5/12
what is the value of x?

Answers

Answer 1

Answer:

x=2

Step-by-step explanation:

subtract 7/9x -4/9x

3/9x= 1/4 +5/12

first change 1/4 to 3/12

then add 3/12 + 5/12

3/9x = 8/12

change 3/9x to 1/3x then to 4/12x

4/12x = 8/12

then mulitiply by the reciprical 12/4 on both sides

x = 2

Find the value of X.
to
67°
56°

Answers

Answer:

x = 57

Step-by-step explanation:

180 degrees in a triangle

67 + 56 = 57

Answer: x = 57

==================================================

Explanation:

The three angles of any triangle always add to 180

x+67+56 = 180

x+123 = 180

x+123-123 = 180-123 .... subtract 123 from both sides

x = 57

The missing angle is 57 degrees

-------------

Check:

x+67+56 = 57+67+56 = 180

Answers

Answer:

Part A:

m∠VHT = 152°

Part B:

m∠QTS = 152°

Part C:

m∠ZHQ = 28°.

Step-by-step explanation:

Part A:

The given parameters are;

m∠HXU = 113°

Segment BQ and segment UD intersect at m∠XAT = 95°

We have that m∠HXU + m∠HXS = 180° (Angles on a straight line)

Therefore;

m∠HXU = 180° - m∠HXS = 180° - 113° = 67°

m∠HXU = 67°

m∠XAT + m∠XAH = 180° (Angles on a straight line)

m∠XAH = 180° - m∠XAT = 180° - 95° = 85°

m∠XAH = 85°

In triangle XAH, we have;

m∠XAH + m∠HXU + m∠XHA = 180° (Angle sum property of a triangle)

∴ m∠XHA = 180° - (m∠XAH + m∠HXU) = 180° - (85° + 67°) = 28°

m∠XHA = 28°

m∠VHT + m∠XHA = 180° (Angles on a straight line)

m∠VHT = 180° - m∠XHA = 180° - 28° = 152°

m∠VHT = 152°

Part B:

m∠QTS ≅ m∠VHT (Corresponding angles are congruent)

∴ m∠QTS = 152° (Substitution property)

Part C:

m∠ZHQ ≅ m∠XHA (Reflexive property)

∴ m∠ZHQ = 28°.

A cube has an edge measuring 4 inches. What is the surface area of the cube, in inches²?

Answers

Answer: 96 in2

Step-by-step explanation: This is because u have to mutiple the two bases and the lateral sides to get your area

The surface area of the cube, in inches² is 96in²

The formula for calculating the surface area of a cube is expressed as:

S = 6L²

L is the side length of the cube

Given that L = 4in. Substitute the given parameter into the formula:

S = 6(4)²

S = 6(16)

S = 96in²

Hence the surface area of the cube, in inches² is 96in²

What compound inequality describes this graph

Answers

Answer:

0≥x<4

Step-by-step explanation:

first, let's look at this number line.

there is a closed circle at 0 and an open circle at 4. this means that 0 is included (≤ or ≥) and that 4 is not included (< or >).

these are the endpoints, meaning that in this compound inequality, the numbers next to the symbols are 0 and 4.

x is in the middle of this compound inequality.

0 x 4

now, we have to figure out the symbols in between. i wrote out our choices above for each number. the highlighted portion is greater than or equal to 0 and less than 4, so we can write this compound inequality as the following:

0≥x<4

x is greater than or equal to 0, but less than 4

(6×10^2) ÷ (3×10^-3)

Answers

Answer:

2*10²

Reduce the expression, if possible, by cancelling the common factors.

Scientific Notation:

Hi!

Lets go through this together.

Using the operation, PEMDAS, we start from left, then go to right.

since there are two pairs of parenthesis, we start with the one on the left.

(6x10^2)

so now, we do the exponent, 10^2

10x10= 100

So our answer for this part is 100.

Now we have (6x100)

6x100=600

So now, the equation is 600÷(3x10^-3)

Now, we do the parenthesis on the right.

(3x10^-3)

First, we do the exponent, 10^-3

10x-10x-10= 1,000

so now, the equation is (3x1,000)

Now, we multiply.

3x1,000=3,000

So now, the equation is 600 ÷ 3,000

600 ÷ 3,000 = 0.2

So, your answer is 0.2.

__________________________________________________________

(6 x 10^2) ÷ (3 x 10^-3)

=(6 x 100) ÷ (3 x 10^-3)

= 600 ÷ (3 x 10^-3)

= 600 ÷ (3 x 1,000)

= 600 ÷ 3,000

= 0.2

(also, the scientific notation is 2x10^2)

Answers

Answer:

x = 30

Step-by-step explanation:

x + 2x + 3x = 180 (Add like terms)

6x = 180 (Divide both sides by 6)

x = 30

Therefore;

x = 30

2x = 60

3x = 90

X=30
3x=90
2x=60

If you are referring m as x then first we need to understand and realize how a triangle will ALWAYS equate to 180°.

With that being said a triangle will always have 3 angles, along with them all being able to be added up at equating 180. In this case all of our angles are related to x. We want to first add up all of our angles to equal 180 (x+2x+3x=180 OR 6x+180.) now that we have our equation, we want to solve for x so we need to isolate x first, in order to get 6 out of 6x we must divide by 6 on both sides of the equation which will then give us 180/6=30.

With x equating to 30 then we simply plug in our values for the angle. 3(30)= 90, 2(30)= 60 and x=30

Perform the composition or operation indicated.f/g(8) Excerpt from Stuff MattersBy Mark MiodownikAt some point humans made the discovery that would end the Stone Age and open the door to a seemingly unlimited supplyof the stuff. They discovered that a certain greenish rock, when put into a very hot fire and surrounded by red-hot embers,turns into a shiny piece of metal. This greenish rock was malachite, and the metal was, of course, copper. It must have beenthe most dazzling revelation. Suddenly the discoverers were surrounded not by dead inert rock but by mysterious stuff thathad an inner life. They would have been capable of performing this transformation with only a few particular types of rock,such as malachite, because getting it to work reliably depends not just on identifying these rocks but also on carefullycontrolling the chemical conditions of the fire. But they must have suspected that those rocks that didn't work, that remainedobstinately rock-like however hot the fire became, had hidden secrets. They were right. It's a process that works for manyminerals, although it would be thousands of years before an understanding of the chemistry required (controlling thechemical reactions between the rock and the gases created in the fire) led to the next real breakthrough in smelting. In themeantime, from around 5000 BC, early metal smiths used trial and error to hone the process of the production of copper. Themaking of copper tools initiated a spectacular growth in human technology, being instrumental in the birth of othertechnologies, cities, and the first great civilizations. The pyramids of Egypt are an example of what became possible oncethere were plentiful copper tools. Each block of stone in each pyramid was extracted from amine and individually hand-carved using copper chisels. It is estimated that ten thousand tons of copper ore were mined throughout ancient Egypt tocreate the three hundred thousand chisels needed. It was an enormous achievement, without which the pyramids could nothave been built, however many slaves were used, since it is not practical to carve rock without metal tools. It is all the moreimpressive given that copper is not the ideal material for cutting rock since it is not very hard. Sculpting a piece of limestonewith a copper chisel quickly blunts the chisel. It is estimated that the copper chisels would have needed to be sharpenedevery few hammer blows in order for them to be useful. Which sentence shows that the human civilization has been positively affected by the discovery of copper A) in the meantime from around 5000 BC early metalsmiths use trial and error to hell in the process of the production of copper be it is estimated that 10,000 tons of copper or for mine throughout ancient Egypt to create the 3000 chisels needed see the making of cover tools initiated a spectacular grown and human technology being instrumental in the birth of technologies cities in the first great civilizations de it is estimated that the copper chisels would have needed to be sharpened every few hammer blows in order to them to be useful Tomatoes will cost more this year.
