Solve the equation: 2 * x-3 = 25, x =? (digit answer):
Answers
is your answer for x
2(x) - 3 = 25
Note the equal sign, what you do to one side you do to the other. Do the opposite of PEMDAS.
First, add 3 to both sides
2x - 3 (+3) = 25 (+3)
2x = 25 + 3
2x = 28
Isolate the x. Divide 2 from both sides
(2x)/2 = (28)/2
x = 28/2
x = 14

Final answer:
The solution to the equation 2 * x - 3 = 25 is x = 14. This is achieved by first adding 3 to both sides of the equation to isolate the term with x, and then dividing both sides of the equation by 2.
Explanation:
To solve the equation 2 * x - 3 = 25 for x, you should start by adding 3 to both sides of the equation to isolate the term with x. This will give us 2 * x = 28. Then, you divide both sides of the equation by 2 to solve for x. This results in x = 14. So, the solution to the equation 2 * x - 3 = 25 is x = 14.

This equation is not possible. All numbers that are squared end up as positive. -6^2 still equals 36 as well as 6^2. Hope this helped!

x=9.
Therefore: |DC| = 2|GD|
|GC| = |GD| + |DC| = |GD| + 2|GD| = 3|GD|
so... we have:
3x + 3 = 3(2x-8)
3x + 3 = 3 × 2x - 3 × 8
3x + 3 = 6x - 24 |subtract 3 from both sides
3x = 6x -27 |subtract 6x from both sides
-3x = -27 |divide both sides by (-3)
x = 9

Answer:
- 508
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 28 and d = - 34 - (- 28) = - 34 + 28 = - 6, thus
= - 28 + (- 6 × 80) = - 28 - 480 = - 508

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.
