they are all correct.
the sum of a number and the quotient of three and seven
To check the expressions, we will substitute some values and simplify the expressions.
1. A number m decreases by 4:
If we assume m = 10, the expression becomes: 10 - 4 = 6.
2. A number d divided by k, minus 6:
If we assume d = 20 and k = 5, the expression becomes: (20 / 5) - 6 = 4 - 6 = -2.
3. A number b less 8:
If we assume b = 15, the expression becomes: 15 - 8 = 7.
4. The sum of a number m and 10:
If we assume m = 12, the expression becomes: 12 + 10 = 22.
5. 18 divided by a number r:
If we assume r = 6, the expression becomes: 18 / 6 = 3.
6. 32 decreased by a number n:
If we assume n = 7, the expression becomes: 32 - 7 = 25.
7. A number k increased by itself:
If we assume k = 9, the expression becomes: 9 + 9 = 18.
By substituting values and simplifying the expressions, we can check if they are correct.
