Answer:

  • $0.04 per cubic foot
  • c(w) = 0.04w +80
  • 3400 cubic feet

Step-by-step explanation:

(a, b) We are given two pairs of values:

 (w, c) = (1900, 156) and (2600, 184)

so we can write the equation of the relationship using the 2-point form of the equation of a line.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  c = (184 -156)/(2600 -1900)(w -1900) +156 . . . . . substitute given points

  c = 28/700(w -1900) +156

  c(w) = 0.04w +80

The charge per cubic foot is $0.04.

__

(c) For a bill of $216, the amount of water used is ...

  216 = 0.04w +80

  136 = 0.04w

  3400 = w

Use of 3400 cubic feet of water would lead to a bill of $216.

Solve the system of equations. (1 point)
DiKsa [7]

Answer: A. (4,1)

Step-by-step explanation:

2x -5y = 3

x -3y = 1

Change the equation to isolate a variable so you can substitute it in the other one.

x = 1+3y so

2(1+3y) -5y = 3

2 + 6y -5y =3

2 + y = 3

y=1

Back to the easy equation we isolated

x = 1+3(1)

x= 4

(4,1) is a point where x=4 and y=1

How many twelfths equal five-fourths
kakasveta [241]

Answer:

15

Step-by-step explanation:

Let n represent the number of twelvths in 5/4.

Expressed symbolically, this is n/12 = 5/4.

The LCD is 12.  Multiply numerator and denominator of 5/4 by 3, obtaining:

n/12 = 15/12.  Then n = 15.

There are 15 twelves in 5/4.
