Which ordered pair is the best estimate of the solution of the system of equations? (i will report you if you answer something incorrect)

(6.8, 2.1)

(6.1, 2.1)

(6.1, 2.9)

(6.8, 2.9)

Step-by-step explanation:

System as per the graphed lines:

The are two solutions.

Solve by substitution.

Substitute y into second equation:

Find y:

The best estimate is x = 6.8 and y = 2.1

Correct choice is A

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
