what is twice the difference of a number and 8 is at least 29

Answer 1

The word, "twice", indicates multiplying by 2 and the word, "difference", indicates subtraction. Also, "is at least" would be greater than or equal to (using x to show the unknown number).

The inequality that would represent the entire problem would be: 2(x - 8) > 29

You can solve this inequality using the distributive property and inverse operations:

2(x - 8) > 29

2x - 16 > 29

2x - 16 + 16 > 29 + 16

2x > 45

2x/2 > 45/2

x > 22.5

Answer 2

Let x = the number

2(x - 8) > 29

2x > 29+16=45

2x >45

x >45/2 = 22.5

x>22.5
