1. 2.27 x 10^-3...when u have a negative exponent, u move the decimal to the left....and since the exponent is -3, u move the decimal 3 spaces to the left.
answer would be : 0.00227. Or the longer way would be : 2.27 * 1/10^3...because if u have a negative exponent, change it to positive and stick it under 1....so 2.27 * 1/10^3 = 2.27/10^3 = 2.27/1000 = 0.00227.

2. 3.772 x 10^5...if the exponent is positive, u move the decimal to the right...and since the exponent is 5...move the decimal 5 spaces to the right....answer would be : 377200...or u could just do 3.772 * 100,000 = 377,200.

3. 9.7 x 10^1 = move decimal to right 1 space = 97
4. 1.33586 x 10^6 = move decimal to right 6 spaces = 1,335,860
5. 1.33586 x 10^-5 = move decimal to left 5 spaces = 0.0000133586
6. 4.22 x 10^-1 = move decimal to the left 1 space = 0.422

X+9=2x-3<br> FIND THE X!!!!!!
Ierofanga [76]

Answer:

x = 12

Step-by-step explanation:

<u>To find "x"</u>, we need to <u>isolate it</u>. This means move "x" to the left side, and everything else to the right side.

When moving a number, do its <u>reverse operation</u> to the entire equation.

x + 9 = 2x - 3

x - 2x + 9 = 2x - 2x - 3         Subtract 2x from both sides

-x + 9 = -3                              

-x + 9 - 9 = -3 - 9           Subtract 9 from both sides

-x = -12

-x/-1 = -12/-1          Divide both sides by -1 to get rid of the negatives

x = 12                     Final answer

Check your answer. Split the equation for the left and right sides. Substitute "x" for the answer "12".

LS:   (left side)

x + 9

= 12 + 9              Add

= 21

RS:   (right side)

2x - 3

= 2(12) - 3            Multiply before subtracting

= 24 - 3               Subtract

= 21

Both sides equal to 21 when "x" is 12.

LS = RS          left side equals right side

Therefore the answer is correct.
