3(2x+5)=3×+4xhow di i solve this step by step

1. distribute the 3 into the parentheses, so you would now have 6x+15=3x+4
2. combine like terms on the right side , so now you have 6x+15=7x
3. subtract the 6 from the left side so it cancels out and also subtract the 6 from the 7 so now you have 15=x
hope this answers your question !

Option D.

Step-by-step explanation:

we know that 20% of the students take Japanese, and we only work with the students that take Japanese, so this 20% will work as our total set, 5% are not in the anime club, and 15% are in the anime club.

Then the percentage of students that are in Japanese and attend to the anime club is equal to the ratio between the percentage that attends to the anime club and the total percentage of students that take Japanese.

P = (15%)/(20%)*100% = 75%
