Aroom in a house is shown on a blueprint. the blueprint has a scale of 5 inches: 8 feet. a wall in the same blueprint has a length of 30 inches. what is the actual length of the wall

48 feet.

Step-by-step explanation:

A room in a house is shown on a blueprint.

The blueprint has a scale of 5 inches = 8 feet.

Therefore, 1 inches = = 1.6 feet

The length of the wall in the blueprint = 30 inches

The actual length of the wall = 30 × 1.6

                                                = 48 feet.

The actual length of the wall is 48 feet.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
