Answer:
29/18
Step-by-step explanation:
-11/6 + m = -2/9
Add 11/6 to both sides.
+11/6 -11/6 + m = -2/9 +11/6
m=29/18
We will check if y and 60cm are parallel.
If the lengths 28cm, 56cm and 15cm, 30cm are in proportion, then y and the segment 60cm are parallel.
OK. We know: y and 60cm are parallel. Therefore we have equation:
<h3>Answer: y = 90 cm.</h3>
