Answer:

area = 375.8 ft^2

Step-by-step explanation:

The scale is 2 inches = 5 feet.

The room is 6.5 inches wide in the drawing. We need the real width, x.

2 in./5 ft = 6.5 in./x

2x = 5 * 6.5

2x = 32.5

x = 16.25

The real width is 16.25 ft.

The room is 9.25 inches wide in the drawing. We need the real length, y.

2 in./5 ft = 9.25 in./y

2y = 5 * 9.25

2x = 46.25

x = 23.125

The real length is 23.125 ft.

Area of rectangle = length * width

area = 23.125 ft * 16.25 ft

area = 375.78125 ft^2

area = 375.8 ft^2

Answer:

x = 2

y = -3

z = 4

( 2 , -3, 4 )

Step-by-step explanation:

x + y + z = 3 ---- i

x – y =5 ---- ii

y - z = -7 ---- iii

ii + iii

x - z = -2 ---- iv

i + ii

2x + z = 8 --- v

iv + v

3x = 6

x = 2

x=2 substitute for v

z = 4

x =2 substitute for ii

y = -3

3x + 2 =11 (solve for x)
torisob [31]

Answer:

x=3

Step-by-step explanation:

first let's try to get just 3x on one side. to do this we can subtract 2 from both side of the equation.

3x+(2-2)=11-2

3x=9

now we have to isolate the variable we can divide both sides by 3:

3x/3=9/3

x=3

and you get the answer that x is 3
