It appears that you have here a list of the # of minutes spent each day on HW, and that y ou need to sum up this list to answer the question. Unfortunately I cannot read the last numeral.
The answer (assuming that my guess is correct) would be found as follows:
Total hours spent on HW in one week = (18+20+22+11+19+18+ ?? )
1) Speed is measured in distance units divided by time units, such as miles per hour. Here, you're given the number of miles traveled and the number of hours it takes, so you can figure tha average speed to be
... speed (or "rate of change") = distance/time = 165 mi/(3 h) = 55 mi/h
2) "speed at the moment" 1.5 hours into the flight means ...
... d. an instantaneous rate of change at 1.5
3) To keep their average speed on target, the dragons must travel at higher than their average speed for a while.
Answer:
the issue will be for 4/5
-pd - pz = -2z + 59
-pz = -2z + 59 + pd
-pz + 2z = 59 + pd
-z(p - 2) = 59 + pd
-z = 59 + pd over p - 2
z = -59 + pd/p - 2.
Send me to equation / question- i find math fairly easy!
