Answer: A! x=-1 2/5, y= 1 3/5

Step-by-step explanation:

First put -3x+3y=9 into slope-intercept form(y=mx+b)

3y=-3x+9

then solve for y

y=-1x+3

enter your y-intercept into the equation below..

2x-7(-1x+3)=-14

2x+7x-21=-14

2x+7x=-14+21(when changing sides it changes signs that's why 21 is now a positive)

2x-7x=7

-5x=7 divide -5 into 7

7/5

x=-1 and 2/5

then input x back into the first equation

-3(7/-5)+3y=9

21/5+3y=9

3y=9-21/5

3y=24/5

divide 3 into 24/5

=24/15=1 and 9/15 reduce it anddd

Admission to a local aquarium is $10 for
adults and $7 for children. The aquarium
collected $6,549 from the sale of 783
tickets. Find the number of adult tickets and
children tickets that were sold.

Answers

First, let's define variables:

A = adults

C = children

Okay, now that's done, time to set up the two equations required to solve:

10a + 7c = 6549

a + c = 783

One way you can solve this is to set up the second equation to isolate a variable. For example,

a = -c + 783

Using this, we can plug it into the first equation and solve for c.

10(-c+783) + 7c = 6549

-3c = -1281

c = 427

Now, use the value of 427and plug it in either equation to solve for a.

a + 427 = 783

a = 356

356 adult tickets were sold, and 427 children tickets were sold.

Which of the following equations are true about the following parallelogram?

Answers

Answer:

A, B, E

Step-by-step explanation:

A is true since the sum of the measures of two consecutive angles of a parallelogram is 180 deg.

B is true since opposite angles of a parallelogram are congruent.

C is false since that equation gives x = -1, but x cannot equal -1 since that would make angle 3x - 12 have a negative measure.

D is false for the same reason as choice C.

E is true since x = 20 is the solution of the equations in choices A and B.

The decimal 0.23 is equivalent to 23/100.

Answers

Answer:

B. No, Jill is not correct, the fraction is equivalent to 0.023.

Step-by-step explanation:

The given fraction is [tex]\frac{23}{1000}[/tex]

Observe that in the denominator there is 1000, which has three zeros after 1.

In changing the given fraction to decimal, there must be 3 significant digits after the decimal.

According to this option (b) is correct.

Moreover, when 23 is divided by 1000, we have

[tex]\frac{23}{1000}=0.023[/tex]

But Jill says that 23/1000 can be written as 0.23, so, Jill is not correct.

Hence option (b) is correct,

How do I find x and what’s the relation ?

Answers

Answer:

X=17

Step-by-step explanation:

Im sorry if this sounds a bit confusing. Im better at doing the math then explaining it. All the angles in that are 90-degree angles and because of that, you can assume that the angle that you trying to find is also 90 degrees. So to find that equation you can do this.

4x+22=90 -22 from both sides.

-22=-22  

you are left with

4x=68 then divide 4 from both sides.

/4=/4

you then get x=17 which is your answer.

Check your answer by plugging 17 into x.

4*17+22=90

The answer is 90 so you are correct.

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.
