If Jenny can read 7 books in 8 days, exactly how many days would it take her to read 20 books?

Step-by-step explanation:

Given,

No. of days taken by Jenny to read 7 books

= 8

So,

No. of days taken by her to read 1 book

Therefore,

No. of days taken by her to read 20 books

= 22.85.....

= 23 days (approx. )

Hence,

Jenny will take 23 days to read 20 books (Ans)

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
