Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.Rob and Julia decided to shoot arrows at a simple target with a large outer ring and a smaller bull's-eye. Rob went first and landed 5 arrows in the outer ring and 5 arrows in the bull's-eye, for a total of 375 points. Julia went second and got 5 arrows in the outer ring and 4 arrows in the bull's-eye, earning a total of 316 points. How many points is each region of the target worth?The outer ring is worth _ points, and the bull's-eye is worth _ points.
Q. Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.Rob and Julia decided to shoot arrows at a simple target with a large outer ring and a smaller bull's-eye. Rob went first and landed 5 arrows in the outer ring and 5 arrows in the bull's-eye, for a total of 375 points. Julia went second and got 5 arrows in the outer ring and 4 arrows in the bull's-eye, earning a total of 316 points. How many points is each region of the target worth?The outer ring is worth _ points, and the bull's-eye is worth _ points.
Define Variables: Define the variables for the points of each region of the target.Let x represent the points for the outer ring.Let y represent the points for the bull's-eye.
Write Equations: Write the system of equations based on the information given.Rob's score: 5 arrows in the outer ring and 5 arrows in the bull's-eye for a total of 375 points.Julia's score: 5 arrows in the outer ring and 4 arrows in the bull's-eye for a total of 316 points.The system of equations is:5x+5y=375 (Rob's score)5x+4y=316 (Julia's score)
Use Elimination: Use elimination to solve the system of equations.We can eliminate x by subtracting the second equation from the first equation.(5x+5y)−(5x+4y)=375−3165x+5y−5x−4y=375−316y=59
Substitute Values: Substitute the value of y into one of the original equations to solve for x. Using Rob's score equation: 5x+5(59)=3755x+295=3755x=375−2955x=80x=16
Verify Solution: Verify the solution by substituting the values of x and y into the second equation.Using Julia's score equation:5(16)+4(59)=31680+236=316316=316The values satisfy the second equation.
