• All her steps are right, and the answer is right as well
Step-by-step explanation:

The monthly cost for 17 hundred of cubic feet is $52.13.
<h3>What is a
linear equation?</h3>
A linear equation is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
Let y represent the bill paid for x HCF of water.
The slope is 1.45, hence m = 1.45.
The monthly cost for 13 HCF is $46.33, hence:
46.33 = 1.45(13) + b
b = 27.48
y = 1.45x + 27.48
For 17 HCF:
y = 1.45(17) + 27.48 = 52.13
The monthly cost for 17 hundred of cubic feet is $52.13.

Answer:
So first you do $0.50 x 3 = 1.5
then you add that to $12.00
$12.00 + 1.5 = 13.5
13.5 is the cost of one pizza.
Since they bought 12:
The total cost of the 12 pizza is $162 <== not important
<u>13.5 divided by 8 is 1.687</u>
<u>round 1.56875 to the nearest cent 1.7 = $2</u>
so each slice costs $2
Answer: 2. 6 X 2 -4
Step-by-step explanation:
Only 2 fits the descriptions, where 6 is multiply 2, 6 x 2. And we subtract 4 from it, 6 x 2 -4.
