Answer:
11.5cm
Step-by-step explanation:
1.2 meters = 120 centimeters
(for the 9 of them, with each being 9.5cm) = 9 * 9.5
=85.5cm
(For The rest of the remaining 3 books): 120cm - 85.5cm
=34.5cm
Each of them would be 34.5 / 3
=11.5cm
1 km = 1000 meters and 1 hour = 3600 seconds.
9x1000= 9000
9000/3600= 2.5
Your answer would be 2.5 meters per second.
-2 or 2 either one

<span>There are 53 dimes in Jonahs piggy bank. You must use algebra to solve for a variable X as follows:
x.10+(91-X).05=7.2
Solving through will yield X =53 which means 91 - 53 = 38.
53*.10 + 38*.05 = $7.20.
Other methods will also work, but this is the most straight forward.</span>
