Answer:
w = -20
Step-by-step explanation:
-
+ 9 = 13
Shift the (+9) to the other side of the equation. (+9) will turn into (-9).
-
= 13 - 9
= 4
Shift the (÷5) to the other side of the equation. (÷5) will turn into (×5).
-w = 4 × 5
= 20
Multiply both sides of the equation by (-1) so that -w will turn into w.
w = (-1) × 20
w = -20
Answer:
The percent of the book has he read is 36.04 %. Hence, the percent of the book has he read is 36.04 % or 36 %
Step-by-step explanation:
change ÷ original amount x100
480÷100= 4.8 = 1%
173÷4.8= 36%

Step-by-step explanation:
Step-by-step explanation:
Given that the first number is
5,555 and
the second number is 4,444
the product of 5,555 and4,444= 24686420
to the nearest thousand 5,555= 6000
to the nearest thousand 4,444= 5000
Therefore the product of 6000 and 5000 is
=6000x5000
=30000000
Answer: The answer is (c) ln 4768 = 5x.
Step-by-step explanation: The given equation is
![e^{5x}=4768.](https://tex.z-dn.net/?f=e%5E%7B5x%7D%3D4768.)
We are to find the logarithmic form of the above equation.
We will be using the following properties of logarithm :
![(i)~\ln a^b=b\ln a,\\\\(ii)~\ln e=1.](https://tex.z-dn.net/?f=%28i%29~%5Cln%20a%5Eb%3Db%5Cln%20a%2C%5C%5C%5C%5C%28ii%29~%5Cln%20e%3D1.)
The solution is as follows:
![e^{5x}=4768\\\\\Rightarrow \ln{e^{5x}}=\ln 4768\\\\\Rightarrow 5x\ln e=\ln 4768\\\\\Rightarrow 5x\times 1=\ln4768\\\\\Rightarrow 5x=4768.](https://tex.z-dn.net/?f=e%5E%7B5x%7D%3D4768%5C%5C%5C%5C%5CRightarrow%20%5Cln%7Be%5E%7B5x%7D%7D%3D%5Cln%204768%5C%5C%5C%5C%5CRightarrow%205x%5Cln%20e%3D%5Cln%204768%5C%5C%5C%5C%5CRightarrow%205x%5Ctimes%201%3D%5Cln4768%5C%5C%5C%5C%5CRightarrow%205x%3D4768.)
Thus, the correct option is (c).
