Ok so you would plug in 18 for the x so it would be 6(18)-12 and then 6x18 is 108 and 108-12=96 so your answer is 96

The correct scientific notation for the number 500.0 is

marishachu [46]

Answer:

The correct scientific notation for the number 500.0 is $500=5.0\times10^2$

Step-by-step explanation:

While writing a large number in scientific notation we do below mentioned two things.

We take any number between 1 and 10
Then we multiply this number with an exponent of 10.

Hence, any number in scientific notation is in the form $a\times10^b$

Here a is any number between 1 and 10.

b is exponent of 10.

Now, writing 500 in scientific notation, we take a = 5

Hence, we have to take b = 2, since 5 multiplied by 100 equas 500.

Thus, we have

$500=5.0\times10^2$
