2x-3y=8 solve for y I don't understand this at all can someone please help??
Answers
Subtract '2x' to both sides:
-3y = -2x + 8
Divide -3 to both sides:
y = 2/3x + 8/3
or
y = 2/3x + 2 2/3

perimeter = 2width + 2 length
102 = 2(x+9) + 2x
102 = 2x + 18 +2x
102 = 4x +18
84 = 4x
21 = x
Length = x = 21 inches
Width = x + 9 = 21 + 9 = 30 inches

Every time you multiply by 10, you move the decimal one place to the right. In this case if you multiply by 10 seven times, the decimal moves 7 places to the right. Now you have
1.06 ... but you can't just change a number so you have to show how your number is equivalent to the original number. You do this with the exponents. If you raise the new number to the -7 exponent, it shows you have to move the decimal 7 places to the left to expand to your original number. So the scientific notation would be...
1.06 × 10^-7
*note- if you move the decimal to the left you would have a positive exponent. If you move it to the right you'll have a negative exponent.
We move the decimal point from the left, until it gets to 1.06. And the point moves 7 times.
= 1.06 × 10⁻⁷ mm in scientific notation.

Basically, you take the coin to the third power because there is a 1/2 chance that the first coin will flip. The second toss has a 1/2 chance, and so does the third one. Because of this, you have to take 1/2 to the 3rd power, which gets you 1/8. Hopefully I helped you a bit!
