First divide top and bottom by 10.
This converts the fraction to 58/114.
Next divide top and bottom by 2.
This converts the fraction to 29/57.
Since 29 is a prime number this is as far as this fraction can be reduced.

So the answer is 29/57.

Set C = R
This means 16X - 20000 = 14X
Add -16X to both sides
-20000 = -2X
Divide both sides by -2
10000 = X

This means that the break even point is 10000 units.

Assume X is the intensity of the radition at 0 meters.
Then 62.5 milliroentgens/hr = 1/(3^2) * X
Solve for X. X = 9 * 62.5 milliroentgens = 562.5 milliroentgens/hr
Now solve for the radiation at 2.5 meters.
R = 1/(2.5^2) * 562.5 milliroentgens = 562.5/6.25 = 90 milliroentgens/hr

I hope this helps you out.

Since X = pi, (3.141592...) I'm going to assume the problem is in radians not degrees.
Substitute pi in for X in the first equation and you get y = 4 sin(pi)
The sin of pi radians is zero.
Therefore, y = 4 * 0 = 0

I hope this helps you out.

Substitute (7 - X) in for Y in the 2nd equation and you get:

X- (7 - X) = -3 => 2X - 7 = -3 => 2X = 4

Solve this for X and you get X =2.

Plug X = 2 back into the first equation and you get Y = 7 - 2 = 5.

Therefore, the answer is X = 2 and Y = 5

I hope this helps you out.

The tax on a property for a shopping center containing 180,000.00 sq. feet is 45,000.00 what is the bill for a stor ein the center that is 4800 sq. feet?

>> 2x2 + 4xy ? 3 and x2 ? 2xy - 4

I'm not sure what symbol the '?' is !!!!!!!!!

Do you mean 2 * x * x + 4 * x * y - 3 and x * x - 2 * x * y -4 ?

Factoring and grouping: (2 * x * x - 1 * x * x) + (4 * x * y + 2 * x * y) - (3 +4)

Simplifying: x * x + 6 * x * y - 7

[7 - (5 - 7(7 - 6) 2)] 6

First perform all the divisions and write the step as follows:
[(0.67)x2 +(0.75)x-5]+[(0.4)x2 + (0.67)x+6]

Then perofrm the multiplications involved...
[1.32 + (-3.75)]+[0.8 + 4.02]

Then perform the additions involved
[-2.43+4.82]

The final step:
[2.39]

This the answer...

The operator precedence are /,X,+,-

Mode is the most frequently occurring value. in this case 29

the answer is 6..

please rate this solution..thanks

4x-(2x-3)=0
=>4x-2x+3=0 ; (after the bracket's oepned and multiplied by - [minus])
=>2x+3=0 ; taken x as common and 4-2=2 i.e. x(4-2) = 2x
=>2x=-3 ; +3's moved on the right-hand side, so it becomes -3
=>x=-3/2 ; 2 has been moved to the right-hand side and divided with -3 i.e 1/2 multiplied by -3 = -3/2

Hence, x = -3/2


Good luck.

Thanks for using FixYa.

There are two Commutative Properties, which are as follow 1) Commutative Property of Addition :-According to it changing the order of addends does not change the sum. That is, a + b = b + a.
2) Commutative Property of Multiplication:- According to it changing the order of factors does not change the product. That is, a × b = b × a.

In an acknoledgement, you should write all the persons' name that helped you and you should write thank you to them

let number be x

47x = -141 is the equation of sentence given above

x can be found out by x = -141/47 = - 3

pls rate the solution if it was helpful

let sqrt of y =x

y to the power negative 1/2 = 1/ sqrt y

so our equation becomes

( 6x + 1 / 6x ) = 37

36x^2 -222 x + 1 =0

the roots of above quadratic equation are

x1=6.1621

and x2 =.0045

therefore y = x^2

y = 6.1621^2 = 37.971

and y=.0045^2 = .00002025

pls rate the solution if it was helpful.post your doubts i f u have any
