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:
12π cubic inches
Step-by-step explanation:
Volume = (4/3)πr^3
V = (4/3)π9
V = (36/3)π
V = 12π
Answer:
D) 1
Step-by-step explanation:
using the distributive property we have ax+a+bx-b-2=0. because the equation is true for all real x, ax=-bx. this means a-b-2=0 and a=-b. a-b-2=0 becomes a=b+2. then we substitute a for -b and get -b=b+2 which becomes 2b=-2 so b=-1. since a=-b, a=1
The answer is 9, hope this helped <3
Answer:
Step-by-step explanation:
2081.25 ; 2312.50 ; 2543.75 ; ..... 7500
a= 2081.25
d = 231.25
2081.25 + (n-1) * 231.25 = 7500
(n -1) *231.25 = 7500 - 2081.25
231.25n - 231.25 = 5418.75
231.25n = 5418.75 + 231.25
231.25n = 5650
n = 5650/231.25 = 565000/23125
n = 904/37
n = 24 years 157 days
