Answer: The new ratio will be 1/4
Explanation: The initial ratio of losses to wins is 3 to 2. If we sum the numer of losses and wins 3 + 2 = 5 games, that means they loss 3 out of 5 games , and they win 2 out of 5 games.
So if they had won twice as many of the games, that is 2*2=4. And since the number of games is the same ( 5 ), then they would have won 4 games and loss only 1.
So the new ratio of losses to wins will be 1 to 4, or expressed in a fraction: 1/4
The main reason behind this is using properties of logarithm .

when solving
There you use multiplication property and make addition to multiplication then you get extraneous solution because in plenty of cases they occur

But
Same happens in case of logarithm
Answer:-25
Step-by-step explanation:
simplify
35% of 60 = (35/100)*60 = 0.35 * 60 = 21
30% of 80 = (30/100)*80 = 0.30 * 80 = 24
24 is greater than 21.
30% of 80 is greater.

one simple way to tell if both equations do ever meet or have a solution is by checking their slope, notice in this case the slopes are the same for both, meaning the lines are parallel lines, however, notice both equations are really the same, namely the 2nd equation is really the 1st one in disguise.
since both equations are equal, their graph will be of one line pancaked on top of the other, and the solutions is where they meet, hell, they meet everywhere since one is on top of the other, so infinitely many solutions.
