3. MGSE8.EE.8: During a chemistry experiment, the temperature of two substances, M and P, each change at linear rates. Substance M starts at 59°F and decreases
5°F every minute. The table shows the data for substance P.

At one point, substances M and P have equal temperatures. What is that temperature?

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.

a natural event such as a flood, earthquake, or hurricane that causes great damage or loss of life.
