Answer:

x = - 4

Step-by-step explanation:

Given

3 - 2 |0.5x + 1.5 | = 2 ( subtract 3 from both sides )

- 2 |0.5x + 1.5 | = - 1 ( divide both sides by - 2 )

|0.5x + 1.5 | = 0.5

The absolute value function always gives a positive value, however, the expression inside can be positive or negative, thus

0.5x + 1.5 = 0.5 ( subtract 1.5 from both sides )

0.5x = - 1 ( divide both sides by 0.5 )

x = - 2 ← solution Manuela obtained

OR

-(0.5x + 1.5) = 0.5 ← distribute parenthesis on left side by - 1

- 0.5x - 1.5 = 0.5 ( add 1.5 to both sides )

- 0.5x = 2 ( divide both sides by - 0.5 )

x = - 4 ← other solution to the equation

Roger wants to carpet a rectangular room with length of 8 3/4 feet and a width of 9 1/3 feet. If he has 85 square feet of carpet
Dima020 [189]

Answer:

12.66 ft^2

Step-by-step explanation:

Given the dimensions of the room are 8\frac{3}{4}=\frac{31}{4} and 9\frac{1}{3}=\frac{28}{3}.

The area of the room =length*width

Area=\frac{31}{4} *\frac{28}{3}

Area=72.33 ft^2

The area of the carpet=85 ft^2

The area of carpet left= Total area of carpet - the area of the room

The area of carpet left= 85-72.33=12.66 ft^2
