Answer:
2. chord theorem; t = 10.5
3. chord theorem; x = 5
Step-by-step explanation:
For both of these problems, the relevant theorem is the "intersecting chord theorem", also referred to as the "chord theorem." It tells you the product of the lengths of the parts of one chord is equal to the product of the lengths of the parts of the other chord.
2. 20t = 10·21
t = 210/20 . . . . divide by 20
t = 10.5 . . . . . . . simplify

3. 10(x +4) = 15(x +1)
10x +40 = 15x +15 . . . . . eliminate parentheses
25 = 5x . . . . . . . . . . . . . subtract 10x+15
5 = x . . . . . . . divide by 5
So first of all write down 82 / 12 and do the problem.Divide 82 / 12.
Next you get the answer which is,based on a calculator,which is <span>6.83333333333.
But because it's money well I'm guessing it could be 6.83 or 6.833 or the real answer.
The question is confusing but I hope I could help :D</span>
-x -2 I think . 3-(-5)= -2 and 2x -3x = -x
the 5 is in the hundreds place, the 7 is in the tens place and the 2 is in the ones place
