Answer:
x=-12
Step-by-step explanation:
2/3x=-8
Multiple both sides by 3/2
x=-24/2
x=-12
The simplified expression that is equivalent to the total distance, in miles, Joy covers is (A) x² + 3x + 5 miles.

What is an expression?</h3>
- An expression or mathematical expression is a finite combination of symbols that is well-formed according to context-dependent norms.
To find the simplified expression:
Given -
- Distance cycled = x² + 7 miles
- Distance ran = 2x miles
- Distance swam = x - 2 miles
Thus,
- Total distance she covers = x² + 7 + 2x + x - 2
- Total distance = x² + 3x + 5 miles
Therefore, the simplified expression that is equivalent to the total distance, in miles, Joy covers is (A) x² + 3x + 5 miles.

Hello!
The degrees in a circle add to 360°
Since WZ is a diameter the angles on one side of the line add to 180°
We know that the angles to the right of WZ add to 180 and the angle of XW is 63.
We add these to get ZWX
180 + 63 = 243
The answer is 243°
Hope this helps!
