Answer:
x = 20
Step-by-step explanation:
x^2 - 4x - 8 = 8
x^2 - 4x - 8 + 8 = 8 + 8
x^2 - 4x = 16
x (x - 4) = 16
x - 4 = 16
x - 4 + 4 = 16 + 4
x = 20
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:-
The answer is -1. This is because you can plug in the negative values to see which ones work.
