Answer: 

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:-


Answer: it D. 1,512
Step-by-step explanation: i hop this helps if it wrong sorry about that
Answer:
Solve equation [2] for the variable z
[2] z = -x + 3y
// Plug this in for variable z in equation [3]
[3] 2x - 2•(-x +3?) = 18
[3] 4x = 18
// Solve equation [1] for the variable x
[1] x = 2y + 1
// Plug this in for variable x in equation [3]
[3] 4•(2?+1) = 18
[3] 0 = 14 => NO solution
Answer:
x= 4
Step-by-step explanation:
Intersecting Chords Formula:
(segment piece) x (segment piece) = (segment piece) x (segment piece)
10*6 = 15*x
60 = 15x
Divide each side by 15
60/15 = 15x/15
4 =x
