HOME IMPROVEMENT Percy is building a deck behind his house. He measures the location for his deck and rounds to the nearest tent
Mila [183]

The cost would be at least $755.1302 to build the deck.

The deck is in the shape of a rectangle. Therefore,

<h3>Area of rectangle</h3>
  • area = lw

where

l = length

w = width

length = 9.4 ft

width = 6.7 ft

area = 9.4 × 6.7 = 62.98 ft²

Therefore,

1 ft² of lumber = $11.99

62.98 ft² of lumber = ?

cross multiply

cost = 62.98 × 11.99 = $755.1302

Which equation, when solved, gives 8 for the value of X?
guajiro [1.7K]

Answer:

Option C: (5/4)x - 2 = (3/2)x - 4

Step-by-step explanation:

A) (5/2)x + (7/2) = (3/4)x + 14

Multiply through by 4 to get;

10x + 14 = 3x + 56

10x - 3x = 56 - 14

7x = 42

x = 42/7

x = 6

B) (5/4)x - 9 = (3/2)x - 12

Multiply through by 4 to get;

5x - 36 = 6x - 48

6x - 5x = 48 - 36

x = 12

C) (5/4)x - 2 = (3/2)x - 4

Multiply through by 4 to get;

5x - 8 = 6x - 16

6x - 5x = 16 - 8

x = 8

D) (5/2)x - 7 = (3/4)x + 14

Multiply through by 4 to get;

10x - 28 = 3x + 56

10x - 3x = 56 + 28

7x = 84

x = 84/7

x = 12

Find the equation of a line perpendicular to y=x-3 that contains the point (2,1)
murzikaleks [220]

Answer:

y = -x + 3

Step-by-step explanation:

y = x - 3   This equation has a slope of 1

A line that would be perpendicular to the above line would then need a slope of -1

If the line has a slope of -1 and passes through (2, 1) then we can plug into

y = mx + b to get the 'b' value

1 = (-1)(2) + b

1 = -2 + b

3 = b

Equation would be y = -x + 3
