2x-7=29
"Seven less than" => minus 7.
"Two times <u>a number</u>" => 2x (x is the unknown number)
"is twenty-nine" => =29
Putting it all together,
-7 + 2x = 29
or
2x-7=29
(if you were wondering x is equal to 18)

Answer:
A.
Step-by-step explanation:
that is the definition of "mean". it cuts the possible outcomes weighed with their probabilities (actual occurrences vs. possible occurrences) in 2 halves.
To solve for x in the given equation;
![5x+7=3x-9](https://tex.z-dn.net/?f=5x%2B7%3D3x-9)
We start by collecting like terms, as follows;
![5x-3x=-9-7](https://tex.z-dn.net/?f=5x-3x%3D-9-7)
When a number crosses the sign of equality, the sign in front of it switches. Positive numbers becomes negative, and vice versa.
We would now have;
![\begin{gathered} 5x-3x=-9-7 \\ 2x=-16 \\ \text{Divide both sides by 2;} \\ \frac{2x}{2}=\frac{-16}{2} \\ x=-8 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%205x-3x%3D-9-7%20%5C%5C%202x%3D-16%20%5C%5C%20%5Ctext%7BDivide%20both%20sides%20by%202%3B%7D%20%5C%5C%20%5Cfrac%7B2x%7D%7B2%7D%3D%5Cfrac%7B-16%7D%7B2%7D%20%5C%5C%20x%3D-8%20%5Cend%7Bgathered%7D)
