First, let's make some variables then make an expression.
Let x = the number of pizzas
Let y = the number of salads
Then 12x = the price for x pizzas
Then 2y = the price y pizzas
Now we can make our expression.
We combine the costs for the pizzas and salads and delivery charge is added.
12x + 2y + 3
Now we have our expression. Replace the x with how many pizzas you bought and replace the y with how many salads you bought.
How much would 6 pizzas and 3 small salads would cost?
12(6) + 2(3) + 3 =
72 + 6 + 3 =
78 + 3 =
81
The answer to this question is $81.

For point b:


Josh has hiked 17 km, which is 2 km away from being 1/2 done.
<span>In a equation, this might look like: 17 + 2 = (1/2)h </span>
<span>where h is the length of the hike. </span>
<span>and solve for h, h = 38 km

Answer:
n = 13.
Step-by-step explanation:
Slope of the line = (10-1)/3-0) = 3
So the equation of the line is:
y - 1 = 3(x - 0)
y = 3x + 1
When x = 4 y = n, so:
n = 3(4) + 1 = 13.
n = 13.
Answer:
The patient owe $1255.6 .
Step-by-step explanation:
As given
A patient's total surgery charges are $1,278.
The patient must pay the annual deductible of $1,000.
The policy states a 80-20 coinsurance. (i.e 20% of the surgery amount is given by the patient .)
20% is written in the decimal form .

= 0.20
20% of patients surgery cost = 0.20 × $1278
= $ 255.6
Patients owe = Deductible cost + 20% of patients surgery cost
= $1000 + $255.6
= $ 1255.6
Therefore the patient owe $1255.6 .
