22) 2*16=32
32-6=26
23)15*1/5=3
24)45*1/5=9
25)7*2=14
14+8=22
26)1/5^2=1/25
1/25*50=2
To find the value of 1 out of all pieces divided, add the ratios.
8+1= 9
Now divide 72 by the total number.
72/9 = 8 (the value of one 1 unit)
Now to find the value of 8 units= 8*8 = 64
Value of 1 unit= 8
Given:
Consider the equation is:
To prove:
by using the properties of logarithms.
Solution:
We have,
Taking left hand side (LHS), we get
![\left[\because \log_ab=\dfrac{\log_x a}{\log_x b}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbecause%20%5Clog_ab%3D%5Cdfrac%7B%5Clog_x%20a%7D%7B%5Clog_x%20b%7D%5Cright%5D)
![[\because \log x^n=n\log x]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog%20x%5En%3Dn%5Clog%20x%5D)
Hence proved.
Answer:
C is the answer usual balance.
D is the correct answer
x+5=10: subtract 5 from both sides the 5 will cancel out leaving x=5
x+5=10
-5 -5
x=5
