How do you write 90.5 in scientific notation?
✍‍

9.05 X 10^1

Step-by-step explanation:

You move the decimal to the left until there is one remaining number before the decimal. Your exponent to the ten is how many decimal places you moved.

If you split the number 90500000 into a coefficient and a power of 10 you do get 90.5 million in exponential form, but there is an indefinite number of possibilities.

Step-by-step explanation:

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
