I believe it might’ve made 2,400 books, because if you divide 70 from 1680 you get 24, meaning it’s pressing about 24 books per hour, if it’s printing twice that you would multiply 48 by 50 and get 2,400.
Step-by-step explanation:
t1 = 1 = 7*1 - 6
t2 = 8 = 7* 2 - 6
t3 = 15 = 7 * 3 - 6
t4 = 22 = 7 *4 - 6
t5 = 29 = 7 * 5 - 6

Answer:
x= -12 & y=24
Step-by-step explanation:
given,
x+y=12.......... equation (i)
2x=3y........eq(ii)
let,
x=12-y.......eq(iii)
from eq(ii)
2(12-y)=3y
y=24
putting the value of y in eq(iii)
x=12-24
x= -12
Let x be the whole number. x^2 is the square of the number. x-1 is the preceding number. And x+1 is the following number.
(x+1)(x-1)=
x^2 + x - x - 1
x^2 -1
Your answer is x^2-1 which is one less that x^2. This also means that the square of any whole number (x^2) is one greater than the product of the preceding (x-1) and the following (x+1).
