Answer:
28%
Step-by-step explanation:
Let number of children be 2x, then number of adults be 3x
Total number is 5x
Let number of children under 10 be 7y, number of children be 3y,
then total number of children is 10y
so 2x = 10y, x = 5y, y/x = 1/5
younger children = children under 10, number is 7y
so the % is 7y/5x = 7/5 * y/x = 7/5 * 1/5 = 7/25 = 28/100 = 28%
The attached table is one that it is convenient for you to memorize as long as you're taking courses involving angles. For the inverse functions, find the column corresponding to the function, then look for the value in that column. The angle at the beginning of that row is the answer to your question.

Answer:
18x + 24 or c
Step-by-step explanation:
450 minutes this month.
10% more next one.
Total for 2 months.
1) Let's find 10% of 450 and add it to 450 to find out how much he reads next month.
450×0.1=45
450+45=495 minutes
2) Now that we know Oliver reads 495 minutes next month, to find the total, we should add the two.
495+450=First month plus second month=945
•°•Oliver, in total, read 945 minutes during the two months.
