Plz show steps i will give 30 points

50-degree temperature is 0 minutes to heat = 50/0 = 50

60-degree temp. is 1 minute to heat = 60/1 = 60

70-degree temp, is 2 minutes to heat = 70/2 = 35

80-degree temp. is 3 minutes to heat = 80/3 = 26 2/3

90-degree temp. is 4 minutes to heat = 90/4 = 22.5

100 degree temp. is 5 minutes to heat = 100/5 = 20

Hope this Helps :)

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
