So negitave 4 times the variable is less than 20.
Answer:
Step-by-step explanation:
Alejandro has read 28 pages so far and he can read 1 page per minute.
Again, Carly has read 12 pages so far and he can read 2 pages per minute.
If the variable N represents the number of pages read by the readers and T in minutes represents the time spent by the reader to read this number of pages, then
For Alejandro: ......... (1)
For Carly: .......... (2)
So, the equations (1) and (2) gives the number of pages that Alejandro and Carly read. (Answer)
Answer:
The original price is $210.
Step-by-step explanation:
p*2/3 -25 = 115
where p is the original price.
p*2/3 = 115 + 25
p*2/3 = 140
p = (140*3)/2 = 210
N is equal to 9 because the 12’s cancel out leaving the 9
Permutation is different from combination because in combination the order is not a factor in considering the possible ways while permutation considers order as a factor. we are asked in this problem to evaluate 3P0 which is equal to 1.
