The answer is x=-80.
First subtract 4 from both sides.
-6=
+4
-6-4=
+4-4
-10=
Multiply 8 on both sides to isolate x.
-10·8=
-80=x
Answer:
Triangle Proportionality Theorem
If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally

Here's our expression: 
We will follow the order of operations and begin by solving everything in parentheses. 
Next, we solve the exponents. 
Now, we solve the multiplication and division. There is no division, so we will just solve the multiplication. 
Finally, we solve the addition and subtraction. Since there is no addition, we will solve the subtraction. 
Put 124m over 29s. Distance/Time = Speed. The answer is 4.27 mps.
