Answe num 3 and 4 plz and thx

41 1/4 and 15

Step-by-step explanation:

So for the first question, we know that a single inch of thread has 16 1/2 bolts. We know that there are 2 1/2 inches of thread.

To find the total anount of bolts in the thread, we can multiply 2 1/2 by 16 1/2:

2 1/1*16 1/2 = 41 1/4

That is our first answer.

For our next answer, we know that a book is 1 7/8 inches big.

The bookshelf is 28 1/8 inches big.

To find how many of the 1 7/8 inch big books can fit in the 28 1/8 inch big bookshelf, we can divide 28 1/8 by 1 7/8:

28 1/8/1 7/8

=

15

So our 2nd answer is 15.

Hope this helps!

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
