Find the value of x that makes m∥n.
Lines m and n are parallel when x=

x=26

Step-by-step explanation:5x+13=143

subtract 13 from both sides 5x+13-13=143-13      

then divide 5 from both sides 5x/5=130/5

after dividing both sides your answer will be x=26

The other number is 22.

Step-by-step explanation:

66 is the lowest common multiple of 6 and a number between 15 and 25.

The numbers between 15 and 25 include 16, 17, 18, 19, 20, 21, 22, 23 and 24.

Of all these numbers between 15 and 25, only 22 can divide 66 without a remainder.

And conveniently, the lowest common multiple of 6 and 22 is 66.

Hence, the other number is evidently 22.

Hope this Helps!!!
