Answer:
f(x) = -x -3
Step-by-step explanation:
960 watts = 24 hours
4 days = 96 hours
960 (watts) x 4 (days) = 3840 watts
12 hours= 480 watts
6 hours = 240 watts
18 hours = 720 watts
3840 (4 days) + 720 (18 hrs) = 4560
2 1/5 hours on homework for math = 2.2
Science homework took 1.1 hours to complete.
2.2+1.1= 3.3
7/8 of an hour is 50 minutes because we know that an hour is 60 minutes and every 10 minutes is a number for the numerator, if that makes sense.
3.3 of an hour plus 50 minutes, would equal 3.8 since the 3 after the point would be minutes. To convert into hours, since an hour is 60 minutes, we have 4 hours and 20 minutes he spent on homework over the weekend. That would be your answer! Hope this helped.
Answer:
Step-by-step explanation:
4x + 9 + 3x + 3 = 33
7x + 12 = 33
7x = 21
x = 3
HJ= 4(3) + 9 = 12 + 9 = 21
JK= 3(3) + 3 = 9 + 3 = 12
34y = 272
34y/34 = 272/34
y = 8
