Step 1: –10 + 8x < 6x – 4 Step 2: –10 < –2x – 4 Step 3: –6 < –2x Step 4: What is the final step in solving the inequality –2(5 – 4x) < 6x – 4?

Given:

The inequality is

To find:

The missing step in solving the given inequality.

Solution:

Step 1: The given equation.

Step 2: Subtract 8x from both sides.

Step 3: Add 4 on both sides.

Step 4: Divide both sides by -2 and change the sign of inequity as we divide the inequality by a negative number.

Therefore, the missing step is .

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
