x = 5/2

x = 2.5

Again hit the ' 2nd ' button in the upper left corner first to convert the keys to their 2nd function

Maybe you want the FRACTION?    60 1/3

..... Its already in a decimal but if you want it shorter it is 60.3 there needs to be a line on top of the 3

b = 14, because if you backtrack it will become14. So b is being dividing by -7 ; -b/7 ; and the answer is -2. The opposite of dividing is multiplying, so you just need to multyply -7 and -2 that is 2 

 Work:

-b/7 = -2 

-7*-2

14

b = 14

A and C are both true   

(I haven't formally proved it which I should do  for absolute certainty)

I think for C it has to be a rhombus as well.

I think what you call a trapezoid, I would call a trapezium and all rhombuses are trapeziums.

Just as all rhombuses are paralellograms.

An isosceles trapezoid has side lengths 13,4,13 and 14. What is the perimeter of its Varignon parallelogram?

I have decided to practice my descriptive skills.

It is important that you develope your comprehension skill in geometry descripions.  SO draw what I am describing and see if you can make sense of it.  If you cannot then ask and I will present some diagrams.  BUT if you try hard enough you probably will not need a diagram.

-----------

Draw the isosceles trapezoid so that the longest side is on the bottom of the pic

You will see that the diagonals of the varigon parallelogram cross at right angles.  So it is not just a parallelogram it is also a rhombus.  You only need to find one side because they are all the same.

If you cut your trapezium into three it is made up of a central rectangle  that is height by 4 units

and 2 congruent right angled triangles that are have a hypotenuse of 13 and one other side 5.

Using pythagoras's theorum it is easy to determine that the height is 12. This is the length of one of the diagonals.

Now consider the one of the congruent triangles.

Half the base is included in the other diagonal and the other half of it is not.  

The base is 5. so 2.5 is inincluded in the other diagonal.  But there are two right triangles so 2.5*2=5 units from the bas are NOT in the other diagonal.

So the diagonal is 14-5=9 units

So the two diagonals of the varignon rhomus are   9 and 12

The half diagonals are 4.5 and 6 units.

Using pythagoras again the legtn of the side of the rhombus will be 7.5 inits

So the perimeter will be 4*7.5 = 30units

1 in^3 = 1/ 1728   ft^3

Hit the  ' 2nd ' key in the upper left corner first....it changes the keys to their  '2nd' function.....

In this case it is "B".

Well, it means 30% of your mortgage is deferred or postponed. It depends on the language in your your mortgage agreement. If you are having financial difficulties in making your monthly mortgage payments, then your lender may "modify" the terms of the mortgage. This defferal sometimes is written off completely. Sometimes, you may have to pay it in the future without any interest. And sometimes you may have to pay it with some interest agreed upon by you and your lender. It can get very complicated depending on the circumstances involved. The best thing to do is to talk to your lender and ask for explanation as to what is involved in this principal defrral.

a function thats linear ;)

Joshua opened a savings account 11 years ago. The interest rate was 2.9% compounded quarterly. If his balance is currently $1,437.34, how much did he originally deposit into the account? 

PV = FV / [ 1 + R]^N

PV = 1,437.34 / [1 + 0.029/4]^(11*4)

PV =1,437.34 / [ 1.0075]^44

PV =1,437.34 / 1.374169

PV =$1,045.97 What Joshua deposited 11 years ago.

Idk

6+ 4/5b= 9/10b    multiply through by 10  to clear the fractions

10 (6)  + (10)(4/5)b  = 10 (9/10)b

60  +  (40/5)b  = 9b

60  + 8b    =  9b      subtract  8b from both sides

60  = 1b  

60  = b 

"A decimal number is a number with a decimal point in it, like these: 1.5 .6 3.14. The number to the left of the decimal is an ordinary whole number. The first number to the right of the decimal is the number of tenths (1/10's)." - Google

6+ 4/5b= 9/10b

1.

\(6+\frac{4}{5b}=\frac{9}{10b}\)

\(\frac{4}{5b}-\frac{9}{10b} =-6 \)

\(\frac{8-9}{10b} =-6 \)

\(-1=-60b\)

\(b=\frac{1}{60} \)

2.

\(6+\frac{4}{5}b=\frac{9}{10}b\)

\(\frac{4}{5}b-\frac{9}{10}b=-6 \)

\(\frac{8b-9b}{10}=-6 \)

\(-b=-60\)

\(b=60\)

Find out the right result, but take the head and not the computer.

2/11m + 16 = 4 + 6/11m

12 = 4/11m

m = 33

2/11m + 16 = 4 + 6/11 m

Rearrange the terms:

16-4 = 6/11 m - 2/11 m

12 = 4/11 m

Divide both sides by 4/11

12/(4/11) = m

33 = m

Well lets see:

6+ 4/5b = 9/10b

6 = 1/10b

b = 60

Sorry but you are incorrect. Where did u go wrong??

From My other post

Well lets see:

6+ 4/5b = 9/10b

6 = 1/10b

b = 60

Sorry but you are incorrect. Where did u go wrong??

Please solve ._. The "/" means a fraction

6+ 4/5b= 9/10b

I tried to solve it and I got 6=b. Please tell me if I am correct or wrong. 

Thanks CPhill!!! Tiring.....!!!
