Answer:
x + .20 = 1
Step-by-step explanation:
The equation would be x + .20= 1, or 1.00, because if you turn 20% into a decimal, it becomes .20. The total you are trying to find is 1 whole, in which this case it would simply be one as there is no other information. The x is first as if you had the .20 first, you would have to divide each side by .20, which would make x = 5, and that would not make sense.
Finding X: To find, subtract on each side by .20 due to the fact you are adding and need to do the opposite, .20-.20 cancels out and 1.00-.20 is .80, so you are left with x=.80
3 dollars pound because since it is 3/4 you can do: 2.25/3 and get 0.75. Thus means 0.75 is 1/4 a pound. 0.75 x 4 will get you dollars for pound. So 3
Answer:
B
Step-by-step explanation:
Got it right on edge. mark me brainliest please
First of all, we need all logarithms to have the same base. So, we use the formula
To change the second term as follows:
Finally, using the property
we have
So, the equation becomes
We can now use the formula
to write the equation as
Now consider both sides as exponents of 2:
This equation has no "nice" solution, so I guess the problem is as simplifies as it can be
