If the ordered pair is a solution, then the two equations in the system should be true after we plug in the points, like so:
(3) + 3(1) = 6 and 4(3) - 5(1) = 7
Then you simplify. 3 + 3 = 6 and 12 - 5 = 7, therefore the ordered pair is a solution of the given system.
19 × 1.03 = 19.57
The answer is 19.57. i hope this helped u cuh

Answer:
B. 10
Step-by-step explanation:
Let x represent pounds of chocolate worth $1.50 a pound and y represent pounds of chocolate worth 90¢ ($0.90) a pound.
We have been given that a mixture contains 30 pounds of both chocolates. We can represent this information in an equation as:
We are also told that a mixture of 30 pounds of candy sells for $1.10 a pound. We can represent this information in an equation as:
From equation (1), we will get:
Upon substituting this value in equation (2), we will get:
Therefore, 10 pounds of the $1.50 chocolate were used to make the mixture and option B is the correct choice.
