At 9:00 am, the temperature at an Arctic observatory was –12 degrees F. By 5:00 pm, the temperature had risen 5 degrees. Over the next three hours, the temperature had dropped 2 degrees. What was the temperature at 8:00 pm?

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

x = 12

y = 1

for the points!
