At your level , just take these to be the meaning of the following :
integer : numbers without fractions or decimal places i.e whole numbers, their negatives and zero
Eg. 5, 10, -6, -1000, 0
Prime number : a whole number greater than 1, and that can only be divided by itself or 1.
Eg. 2, 3, 5, 7, 13, 17, 19, 101
Rational numbers : can be expressed as a fraction or mixed number
Eg. ⅔, 5( = 5/1 , 10/2, 250/50), 1.5 ( = 3/2 or 1½)
integer : numbers without fractions or decimal places i.e whole numbers, their negatives and zero
Eg. 5, 10, -6, -1000, 0
Prime number : a whole number greater than 1, and that can only be divided by itself or 1.
Eg. 2, 3, 5, 7, 13, 17, 19, 101
Rational numbers : can be expressed as a fraction or mixed number
Eg. ⅔, 5( = 5/1 , 10/2, 250/50), 1.5 ( = 3/2 or 1½)
4(x - 7) + 2x ≤ 11
4x - 4(7) + 2x ≤ 11
4x - 28 + 2x ≤ 11
6x - 28 ≤ 11
6x ≤ 11 + 28
6x ≤ 39
x ≤ 39/6
x ≤ 6½
4x - 4(7) + 2x ≤ 11
4x - 28 + 2x ≤ 11
6x - 28 ≤ 11
6x ≤ 11 + 28
6x ≤ 39
x ≤ 39/6
x ≤ 6½
So,
Largest possible integer value of x = 6
Largest possible prime number that x can be = 5
Largest possible rational number that x can be = 6½
Largest possible integer value of x = 6
Largest possible prime number that x can be = 5
Largest possible rational number that x can be = 6½
