The pictures aren’t clear..
A + 4 = 8
a = 4
Can you add anything else to 4 to get 8? No.
4 - m = 2
-m = -2
m = 2
Can you subtract anything besides 2 from 4 to get 2? No.
So the statements are always true.
The hypotenuse leg theorem states that any two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles.
The triangles ΔLNO and ΔLMO have the same leg Lo, therefore you need the equality of hypotenuses LM=LN.
Part A:
Given that forty percent of the players on a soccer team are experienced players.
Then, the o<span>riginal ratio of experienced to total players is given by 40/100 = 4/10
Part B:
Given that t</span><span>he expression

represents the percent of experienced players on the team after the coach adds x experienced players.
Then, the </span>f<span>inal ratio of experienced to total players is given by:

Part C:
Given that </span>t<span>here are 10 players on the team now, and that </span><span>the coach adds x experienced player, then the number of players on the team now is given by:
10 + x.</span>
