3 1/3(2 1/5x-4 2/3)-5 5/6=0
Since you can't subtract 2 1/5x and 4 2/3 together you would use the next step in the order of operations which is multiplication.
(3 1/3)(2 1/5x)=(10/3)(11/5x)=110/15x
(3 1/3)(4 2/3)=(10/3)(14/3)=140/9
7 5/15x - 15 5/9
Then you would subtract 7 5/15x - 15 5/9 with 5 5/6.
7 5/15x -15 5/9 - 5 5/6=
15 5/9=15 10/18
5 5/6=5 15/18
7 5/15x - 15 10/18 - 5 15/18=
7 5/15x - 21 7/18=0
Then you would try to solve for x by isolating it on one side.
7 5/15x=21 7/18
110/15x=385/18
x=(385/18)(15/110)
x=5775/1980
x= 2 1815/1980
x= 2 363/396
x= 2 121/132
x= 2 11/12
I hope you understood!!!!

Answer:

1646/1

Step-by-step explanation:

To write 1646 as a fraction you have to write 1646 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

1646 = 1646/1 = 16460/10

Use the properties of logarithms to prove log, 1000 = log2 10.
Leto [7]

Given:

Consider the equation is:

\log_81000=\log_210

To prove:

\log_81000=\log_210 by using the properties of logarithms.

Solution:

We have,

\log_81000=\log_210

Taking left hand side (LHS), we get

LHS=\log_81000

LHS=\dfrac{\log 1000}{\log 8}                  \left[\because \log_ab=\dfrac{\log_x a}{\log_x b}\right]

LHS=\dfrac{\log (10)^3}{\log 2^3}

LHS=\dfrac{3\log 10}{3\log 2}                   [\because \log x^n=n\log x]

LHS=\dfrac{\log 10}{\log 2}

LHS=\log_210                    \left[\because \log_ab=\dfrac{\log_x a}{\log_x b}\right]

LHS=RHS

Hence proved.

Aleksandr [31]
 5 (3m+2p) -4m= 15m +10p -4m
=11m +10p
--------------------------------------------------------
13p+11m-3p=10p -11m
-----------------------------------------------------------
Yes, 5 (3m+2p) -4m is  equivalent to the expression 13p+11m-3p as i worked out for you.. Hope this helps you!!! =')

(1 - cos ß)(1 + cos ß) =1/cosec^2(ß)
iVinArrow [24]

Step-by-step explanation:

L.H.S=(1-cosB)(1+cosB)

=(1-cos^2B). {using (a+b) (a-b)=(a^2-b^2)in second step}

=sin^2B

=1/cosec^2B

Therefore,L.H.S=R.H.S proved

Which line plot displays a data set with an outlier?<br><br> Plz answer quickly!
iren2701 [21]
The answer is the first data set because remember, an outlier is a number in a data set that is extremely far away from all of the other numbers.

You can easily tell which one is the outlier, the first data set's outlier is 13, because it is was placed so far away from the other data points.

We know that the first data set is correct because all of the other data sets have numbers that are clustered together.

~Hope I helped!~
