Yesterday, the temperature at noon was 10.4°F. By midnight, the temperature has decreased by 16.7 degrees. What was the temperature at midnight? I'm in 7th grade by the way

-6.3 degrees

Step-by-step explanation:

First I formed the equation 10.4-16.7=x, which the answer came to be -6.3 degrees.

It is 6 $ per hour and you need to make 40 hours you would multiply 6 *40 = 240so s = 240 + 9ypart c: substitutesince andrew earned 330 you would substitute it for s 330 = 240 + 9y < solve for y330 ( - 240 ) = 240 ( - 240 ) 9y < subtract 240 from each side 90 = 9y 90 / 9 = 9y / 9 < divide by 9 10 =y andrew worked 10 hours for overtime check 330 = 240 + 9(10)330 = 240 + 90 330 = 330 < -- your answer is 10
