<h3>Answer:   0.0000000651</h3>

There are seven "0"s between the decimal point and the digit "6".

======================================================

Explanation:

The number 6.51 \times 10^{-8} is in scientific notation.

The exponent -8 tells us to move the decimal point exactly 8 spots to the left to get the answer 0.0000000651

In other words, we'll move the decimal point one spot to the left to go from 6.51 to 0.651

Then we move it another seven spots to the left to arrive at 0.0000000651

This is why there are seven "0"s between the decimal point and the digit "6".

PLEASE HELP!!
trapecia [35]
First, solve for x. Isolate the x. Do the opposite of PEMDAS.

2x + 4 = 8

Note the equal sign. What you do to one side, you do to the other.

subtract 4 from both sides

2x + 4 (-4) = 8 (-4)

2x = 8 - 4

2x = 4

divide 2 from both sides

2x/2 = 4/2

x = 4/2

x = 2

you know you're starting number now: 2

"then add it to two": 2 + 2 = 4
"then add it to ten": 4 + 10 = 14
"then subtract three": 14 - 3 = 11
"then add ten": 11 + 10 = 21

21 is your final answer


hope this helps
