We have been given that Emanuel starts deleting 20 pictures every day. The number of pictures deleted in d days will be .
We have been given that Emanuel has 745 pictures in his phone. The number of pictures left after d days would be initial number of pictures minus number of pictures deleted in d days.
Therefore, the expression represents number of pictures left on Emanuel's phone after any given number of days.
One variable is the amount of days. Lets call the amount of days D. Another variable is the amount of pictures left. Lets call this p. In this case, since Emanuel is deleting 20 pictures a day, and he has 745 picture to start with, the equation would be 745- 20D=p.
The only thing that needs translation to symbols is "greater than". Your "word sentence" already uses the symbols x and 0. The symbol for greater than is >. Your inequality is ...
(7 + 2i)(-3 - 4i) Take the 7 then times it buy the second bracket 7x(-3-4i) then take 2i from the first bracket and times it with the second bracket 2ix (-3-4i)
you organize the numbers from smallest to biggest from there you find the middle and if there is no middle get the two middle numbers and add them from there you divide what you got by 2
