Use 15+x=the final temperature
Answer:
15 to 27 (which is equal to 5:9)
Step-by-step explanation:
The ratio 15 to 12 indicates that there is a total of 27 people in the classroom (15+12). So, if you want boys to total students, it's 15 to 27.
You can divide each of these by 3 to simplify it and get 5:9.
24/55 is the answer
You can either use a calculator on your phone or computer
80%x + x = 216
0.8x + x = 216
1.8x = 216
x = 216/1.8
x = 120
