The inequality to represent this situation is |x - 76| < 5.
The temperature of her house is set at 76° Fahrenheit. The temperature might vary at 5 degrees. This simply means the temperature might increase by 5 degrees or decrease by 5 degrees.
Therefore, the inequality to represent this situation can be represented below:
|x - 76| < 5
-5 < x -76 < 5
add 76
-5 + 76 < x -76 + 76 < 5 + 76
71 < x < 81
Therefore, the inequality to represent this situation is |x - 76| < 5.

4 and 5 is it in its simplest form
Answer:
x = 0
Step-by-step explanation:
Step 1: Write equation
3x - x + 4 = 4(2x + 1)
Step 2: Solve for <em>x</em>
- Distribute: 3x - x + 4 = 8x + 4
- Combine like terms: 2x + 4 = 8x + 4
- Subtract 2x on both sides: 4 = 6x + 4
- Subtract 4 on both sides: 0 = 6x
- Divide both sides by 6: x = 0
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
3(0) - 0 + 4 = 4(2(0) + 1)
4 = 4(1)
4 = 4
