Given that:
Miles traveled the fastball in 2 seconds = 60.5 ft
So, the ball traveled in one second

The ball travels 30.25 miles per second.
The word partition means "division into shares". In Math, partition in number theory is a method of writing numbers as a sum of positive integers. Each integer is called a part or a summand. The order of the summand matters, thus making the sum a composition.
Partition function represents the possible number of partitions of a number (natural number <em>n</em>), or the number of distinct and order-independent methods of illustrating n as a sum of natural numbers.
Young diagram can be used to represent integer partitions.
Partition of numbers is taught to children specially the young ones to split large numbers to smaller units. This can be done in four different ways. For instance: 1 + 4, 1 + 1+ 1 + 2, 1 +3 +1 and 3 + 1 + 1.
X - 3 < -9 x + 5 > = 12
x < - 9 + 3 x > = 12 - 5
x < - 6 x > = 7

-1 = z/3 - 7
Emily's Work:
-1 = z/3 - 7
-1(3)=z/3(3)-7
-3 = z - 7
-3 -7 = z - 7
z = -10
Right away without having to start at the beginning, I see that she has made a mistake at the 4th-5th line of work.
Instead of adding 7 to both sides, she subtracts it and still leaves it in and doesn't fully finish the equation, as it would really be z-7 = -10
In order to solve it, follow these steps:
Rewrite the initial equation as follows:
x/3 - 7 = -1
Multiply both sides by 3
x/3(3)-7(3)=-1(3)
x - 21 = -3
Add 21 to both sides
x = 18
