The inequality which represent, the difference of seven and two tenths and a number is more than twenty-nine, is
Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.
Inequality is represented with the greater then(<), less then(>) or with the other inequity signs like less than equal to or greater than equal to
.
Tenth is written as the fractional part of the number 10. The value of one tenth is equal to 1/10 or 0.1.
The sentence given for the inequality expression is, that the differences of seven and two tenths, and a number is more than twenty-nine.
The number seven and two tenths can be written as,
Suppose the unknown number is n. Now, the differences of seven and two tenths, and this number (<em>n</em>) is more than twenty-nine. The more than word means, the greater than sign for equation. Thus, it can be expressed as,
Hence, the inequality which represent, the difference of seven and two tenths and a number is more than twenty-nine, is

Answer:
Option E is correct.
12 pairs of socks and 15 pairs of shorts did team buy each year.
Step-by-step explanation:
Let the number of pairs of socks be x and the number pairs of shorts be y.
As per the statement:
Last year, the volleyball team paid $5 pair for socks and $17 per pair for shorts on a total purchase of $315.
⇒ .....[1]
It is also given that: This year they spent $342 to buy the same number of socks and shorts, because the socks now cost $6 a pair and the shorts cost $18.
⇒ .....[2]
Multiply equation [1] by 6 both sides we get;
.......[3]
Multiply equation [2] by 5 both sides we get;
.....[4]
Subtract equation [4] from [3] we get;
Divide both sides by 168 we get;
y = 15
Substitute the given values of y =15 in [1] we get;
5x+17(15) = 315
5x + 255 = 315
Subtract 255 from both sides we get;
5x = 60
Divide both sides by 5 we get;
x = 12
Therefore, 12 pairs of socks and 15 pairs of shorts did team buy each year.
