Since the shape is a square the sides are equal. Then we need to find x such that x * x = 169.
Sqrt(169) = 13
So x = 13
So for me, how I would do it is move the variables and numbers to one side. So we have the equation 3x-3=2/5x+7. So you would subtract 2/5x to the left side and add 3 to the right side. The equation will then turn out to be 3x-2/5x=7+3. Much more easier right? So just simplify both side, and you will get 13/5x=10. In order to isolate x, you have to divide 13/5 in both side, leaving x= 3 11/13 or 50/13. You can always plug the answer back in to double check :)

Answer:
The correct answer is 30
Step-by-step explanation:
Given: The x-axis represents the time in hours and the y-axis represents the distance in miles.
The line passes through the points 
and 
To find: The rise-over-run value for the relationship in the graph.
Thus, the rise-over-run value for the relationship represented in the graph is 30.
You have to find a common denominator for the fractions. 5 and 7 both go into 35 which is the lowest common multiple of 5 and 7. 2/5 is multiplied by 7/7 and 3/7 is multiplied by 5/5. Then add the two fractions. So 29/35 parts are finished of the total number of bracelets.
