Flour costs $0.80 per pound and sugar costs $0.50 per pound. an order of flour and sugar weighs 15 pounds and costs $9.00. make a system of equations?i really need your .

Step-by-step explanation:

Let x be the amount of flour and y be the amount of sugar ordered.

Since, the order of flour and sugar weighs 15 pounds.

Therefore,

Also, Flour costs $0.80 per pound and sugar costs $0.50 per pound.

The cost of ordered flour=$0.80x

The cost of ordered sugar=$0.50y

Now, the total cost of the order=

Hence, for the given situation the system of equations is:-

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
