Answer:
The correct answer is x = 4.
Step-by-step explanation:
If A is the midpoint of CT, this means that CA is equal to AT. This also lets us know that CA is half of CT. This lets us write the following equation:
CA = 1/2(CT)
Now, we can substitute the values we are given into the equation above.
7x – 5 = 1/2 * (46)
If we simplify the right side of the equation, we get:
7x – 5 = 23
The next step is to add 5 to both sides of the equation. This gives us:
7x = 28
Finally, we can divide both sides of the equation by 7.
