If l: m = 5/2 : 5/3 and m:n = 5/4 : 7/2 find l:m:n .

1 answer:

4 0

Try this solution:1. If l/m=5/2:5/3, then l/m=3/2 and l=3/2 m;2. If m/n=5/4:7/2, then m/n=5/14 and n=14/5 m;3. l/m/n= 3/2 m: m: 14/5 m; ⇒ l/m/n=3/2:1:14/5 (or l/m/n=15/10/28).

What's (-5, 3) reflected along x-axis

Anna71 [15]

Whenever you reflect a point over the x axis, the x coordinate stays the same and the y coordinate is negated. In this case, the y coordinate which is 3 will be negated to become -3, and the x coordinate which is -5 will remain the same. Therefore, the new point is (-5,-3).

I hope this helps.
