Answer 1

The temperature of a substance in a laboratory beaker dropped thirteen and one-half degrees Fahrenheit from its starting temperature, ending at sixty-eight and three-fourths degrees Fahrenheit. Let s equal the starting temperature. Which mathematical equation could be used to determine the starting temperature of the substance?

s plus thirteen and one-half equals sixty-eight and three-fourths

s plus sixty-eight and three-fourths equals thirteen and one-half

s minus thirteen and one-half equals sixty-eight and three-fourths

s times sixty-eight and three-fourths equals thirteen and one-half
