The answer is x = 3 because is we substitute 3 for x, we get 6 on both sides. 3(3) - 3 = 2(3) (=) 9 - 3 = 6 (=) 6 = 6.
Answer:
x = 18
Step-by-step explanation:
To write a proportion, we need to write down the data we have.
Shorter side of rectangle 1 = 6
Longer side of rectangle 1 = 13
Shorter side of rectangle 2 = x
Longer side of rectangle 2 = 39.
A proportion representing this would be:
Solving this proportion for x, we would have:
Therefore, the shorter side of the second rectangle is 18.

Answer:
81/100
Step-by-step explanation:
Here's how to convert 0.81 to a fraction...
There is not much that can be done to figure out how to write 0.81 as a fraction, except to literally use what the decimal portion of your number, the .81, means.
Since there are 2 digits in 81, the very last digit is the "100th" decimal place.
So we can just say that .81 is the same as 81/100.
So your final answer is: 0.81 can be written as the fraction 81/100
