Math Problem Statement

seven more than five sixths of a number is more than negative three

Solution

We are tasked with solving the inequality:

"Seven more than five sixths of a number is more than negative three."

Let's define the unknown number as xx. We can then translate the problem into an inequality.

  1. "Five sixths of a number" is written as 56x\frac{5}{6}x.
  2. "Seven more than that" means we add 7: 56x+7\frac{5}{6}x + 7.
  3. The inequality "is more than negative three" is written as >3> -3.

So, the inequality becomes: 56x+7>3\frac{5}{6}x + 7 > -3

Step 1: Isolate the term with xx

Subtract 7 from both sides: 56x>37\frac{5}{6}x > -3 - 7 56x>10\frac{5}{6}x > -10

Step 2: Eliminate the fraction

Multiply both sides of the inequality by 6 to get rid of the denominator: 5x>605x > -60

Step 3: Solve for xx

Divide both sides by 5: x>12x > -12

Final Answer:

The solution to the inequality is x>12x > -12.

Here are 5 related questions:

  1. What happens if the inequality were "less than" instead of "more than"?
  2. How would you solve this if the number were represented as a decimal?
  3. What if the coefficient of xx were a fraction other than 56\frac{5}{6}?
  4. Can you rewrite this inequality in terms of absolute values?
  5. What if we change the constant from 7 to a different number?

Tip: When solving inequalities, remember that if you multiply or divide by a negative number, the inequality sign flips.
