EastWind [94]

Answer

Find out the total monthly charges for x cubic feet of water used .

To prove

As given

A water company charges a connection fee each month of $22 and an additional $2.30 per cubic foot of water used.

Than the equation become

Total monthly charges for x cubic feet of water used = Monthly connection fee + charges for x cubic feet of water

thus

f(x) = 22 + 2.30x

where x is the x cubic feet of water used .

Therefore Option (B) is correct i.e f(x) = 22 + 2.30x .

Solve the proportion to determine the value of x. <br><br> 2x / 5 = x+3 / 3

ale4655 [162]

When you solve a proportion, your first step should be to cross-multiply.

$\frac{2x}{5}$ = $\frac{x + 3}{3}$

When you cross-multiply, you should get this equation:

(2x)(3) = (x + 3)(5)

Now, solve it using algebra.

(2x)(3) = (x + 3)(5) Multiply
6x = 5x + 15 Subtract 5x from both sides
x = 15

The value of x is 15.
