5^{(x + 1) / (1 - 2x)}  <  0.3^-3

5^{(x + 1) / (1 - 2x)}  <  125

5^{(x + 1) / (1 - 2x)}  <  5³

(x + 1) / (1 - 2x)  < 3

(x + 1)   <   3(1 - 2x)

x + 1   <   3 - 6x

7x   <   2

x   <   2/7

5^((x+1)/(1-2x)) < 0.2^-3

5^((x+1)/(1-2x))<125. Cannot be reduced further, I think.

1 USD=1.20AUD, or the reciprocal of that:

1AUD = 1 / 1.2 =.8333333......USD, so

22AUD x .8333333 =$18 1/3 USD, or

22AUD / 1.2 =$18 1/3 USD

Damien: Most of your questions appear to be about thermodynamics. Only Alan is competent enough to be able to answer Physics questions. Also, it would be helpful if you gave us some formulas from your Textbook, about the relationships of various states and substances to each other, such as heat, temperature.....etc.

Please respond 

7.2x - 4.8 > 24 multiply both sides by 10

72x - 48 > 240 add 48 to both sides

72x > 288 divide both sides by 72

x > 4

One dime is ten cents. 7.30 is 730 pennies, and a penny is only one cent. Therefore, in order to turn those into dimes, we must divide those pennies into groups of ten. Each group will equal one dime. This is mathemetically represented by 730 divided by 10 (730 / 10), or 73. From this, we can see that there are 73 groups of 10 pennies, or 73 dimes.

how many dimes are there in $7.30

$7.30 x 100 =730 cents

730 / 10 = 73 dimes

10-(2y-6)-y=?. You have to set your equation to equal 0, like this:

Solve for y:
16-3 y=0

Subtract 16 from both sides:
(16-16)-3 y=-16

16-16=0:
-3 y=-16

Divide both sides of -3 y=-16 by -3:
(-3 y)/(-3)=(-16)/(-3)

(-3)/(-3)=1:
y=(-16)/(-3)

The sign of (-16)/(-3) is positive, so (-16)/(-3) = 1×16/3:
Answer: |  y=16/3

Most of the solutions are "complex solutions". However, through iteration and interpolation, there is ONE real solution that appears to balance the equation.

dont need anymore i solved it...

it would infinately digest it

The reason nobody answered your question is because not many people know about "Frieze Patterns", because these patterns are best known through the art of the Dutch artist, M. C. Escher.

Read this article and search the Web to see if you can find help elsewhere. Good luck.

-7 belongs to "Negative Numbers -" on the Number Line.

Simplify the following:
(8 y-10 z)/2-(3 y+z)

Put each term in (8 y-10 z)/2-(3 y+z) over the common denominator 2: (8 y-10 z)/2-(3 y+z) = (8 y-10 z)/2+(2 (-3 y-z))/2:
(8 y-10 z)/2+(2 (-3 y-z))/2

(8 y-10 z)/2+(2 (-3 y-z))/2=((8 y-10 z)+2 (-3 y-z))/2:
(8 y-10 z+2 (-3 y-z))/2

2 (-3 y-z)=-6 y-2 z:
(8 y-10 z+-6 y-2 z)/2

Grouping like terms, 8 y-10 z-6 y-2 z=(8 y-6 y)+(-10 z-2 z):
((8 y-6 y)+(-10 z-2 z))/2

-10 z-2 z=-12 z:
(-12 z+(8 y-6 y))/2

8 y-6 y=2 y:
(2 y-12 z)/2

Factor 2 out of 2 y-12 z:
2 (y-6 z)/2

(2 (y-6 z))/2=2/2×(y-6 z)=y-6 z:
Answer: |  y - 6z

The GCF is 7

Comma in Math, is used to separate thousands like this=125000000000=125,000,000,000.

how do I figure 8% of a number

8% means=8 / 100 =.08. then you multiply this by ANY number that you want. Example: what is 8% of 125 =8/100 x 125 =10. And that is it.
