Answer:
$550
Step-by-step explanation:
In this question, we have to find how much a party would cost for 80 people.
We know that our equation is C = 6.50x + 30
"x" is the amount of people.
To found our answer, we would plug in 80 to "x" to find the total cost.
Solve:
C = 6.50(80) + 30
C = 520 + 30
C = 550
This means that the cost of the party for 80 people would be $550.
Answer:
y=0/-6x-3 or Undefined
Step-by-step explanation:
Since the slope is only a vertical line, that means the slope is going to be undefined. However, this is what the equation would look like.
Hope this helped!
Answer:
7x-48
Step-by-step explanation:
we want our equation to look something like this
y=mx+b
let's start by solving for m (the slope) using the slope formula

Which means, so far, our equation looks like this
y=7x+b
now we just need to solve for B
We can do this by plugging in a set of coordinates
-6=7*6+b
-6=42+b
-48=b
which means our equation is
7x-48
Answer:
answer "Less than"
Step-by-step explanation:
a) 1 2/3 = 5/3 = 1.666 ...
b) 1 5/6 = 11/6 = 1.833 ...
a < b
Answer:
50 kg water.
Step-by-step explanation:
We have been given that the number of kilograms of water in a human body varies directly as the mass of the body.
We know that two directly proportional quantities are in form
, where y varies directly with x and k is constant of variation.
We are told that an 87-kg person contains 58 kg of water. We can represent this information in an equation as:

Let us find the constant of variation as:



The equation
represents the relation between water (y) in a human body with respect to mass of the body (x).
To find the amount of water in a 75-kg person, we will substitute
in our given equation and solve for y.



Therefore, there are 50 kg of water in a 75-kg person.
