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.
The negative of it would be the positive so the answer is 1/4
To find the solution, simply take 3 and divide it by 12. 3/12 as a fraction would be simplified down to 1/4 or 0.25. Therefore, each student would receive one quarter of a pizza.
Answer:
Step-by-step explanation:
4x^2-8x-5=0
The discriminant is the number under the √. In this case it's 144
<span>C = total calories burned
r = rate of burning calories = 420 calories burned/hour
t = time in hours
C = 420 * t
