Hey guys it’s ya boo skinny penus
<span>rate = distance/time
</span>r =
so it would be
r = miles per minute
Or if it was miles per hour:
Cross multiplication gives us
45x = 240
mph
Answer:
The value of x is about 2.206.
Step-by-step explanation:
Consider the given equation is
We need to find the value of x.
Using the properties of logarithm we get
![[\because \ln a^b=b\ln a]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cln%20a%5Eb%3Db%5Cln%20a%5D)
![[\because \ln (ab)=\ln a+\ln b]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cln%20%28ab%29%3D%5Cln%20a%2B%5Cln%20b%5D)
![[\because \ln 1=0]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cln%201%3D0%5D)
On comparing both sides we get
Using graphing calculator, the real solution of the above equation is
Therefore, the value of x is about 2.206.
The <em><u>correct answers</u></em> are:
substitution property; subtraction property of equality; division property of equality; and reflexive property.
Explanation:
The difference between the given statement and the first statement is that 11x is replaced with 88. This is because we are told that x=8; 11(8) = 88. Substitution has been used here.
The difference between the first step and the second step is that 88 is no longer on the left hand side and the right hand side is -89. This is because to cancel 88, it has been subtracted from each side of the equation. This is the subtraction property of equality.
The difference between the second step and the third step is that -6 is no longer on the left side and the right hand side is 89/6. This is because to cancel -6 both sides were divided by -6. This is the division property of equality.
The difference between the third step and the last step is that the 89/6 and y have been flipped around the equals sign. This is the reflexive property.
314 – 302 =12 / 5 = 2.4,
the population grows 2.4 percent of people a year.
