Answer:
12.5x =10x+10
12.50x=x10+10
subtract 10x from both sides
2.5x=10
divide by 2.5
x=4
Answer:
This is not a triangle
Step-by-step explanation:
If you use the triangle inequality theorem you can reach your answer.
The theorem states that if you add the length of any 2 sides together, you will have a length greater than the length of the other side. Using this method we can easily see that 7+6=13 which is less than 21. Meaning this is not a triangle
If x equals the number, then seven times the number is 7x; three less than that is 7x-3.
