Actually, it is
pages left=total pages-pages read
pages read=(number of pages per hour) times (number of hours)
numbe rof pages per hour=40
x=number of hours
254=total pages
so
y=254-40x, not 4x


what is the question
if it is how many hours to read the book then
0=pages left
0=254-40x
add 40x to both sides
40x=254
divide by 40
x=6.35
6.35 days or aprox 7 days


equation is y=254-40x where y=pages left and x=number of hours read

In the recursive formula an = an−1 + 5, the value of the previous term is represented by
den301095 [7]

Step-by-step explanation:

In the recursive formula an = an−1 + 5

a_n = a_{n-1}+5

Suppose if a_5 is the nth term then previous term is a_4

To get the previous term we need to subtract 1 from the n

So a_n is the nth term

a_{n-1} is the previous term

Here 5 represents the common difference between two terms

So value of previous term is represented by

a_{n-1}

Answer : a_{n-1}

All real solutions

Everything cancels out once you multiply the top equation by two.
0 = 0 which means all real answers.
I hoping you meant question 3. Good luck!

Answer:

14.13 in³

Step-by-step explanation:

Volume of a ball (sphere) is:

V = ⁴/₃ π r³

Circumference of a ball (circle) is:

C = 2π r

Use the circumference to find the radius.

9.42 in = 2π r

r = 1.50 in

Use the radius to find the volume:

V = ⁴/₃ π (1.50 in)³

V = 14.13 in³
