Answer:
x = -1
y = 1
Step-by-step explanation:
x = 6y - 7
4x + y = -3
substitute x for 6y - 7 in the second equation
4x + y = - 3
4(6y - 7) + y = -3
open the parenthesis
24y - 28 + y = -3
combine like terms
25y - 28 = -3
add 28 to both sides of the equation
25y - 28 + 28 = -3 + 28
25y = -3 + 28
25y = 25
y = 1
now that you know y is 1, substitute it back into either equation
x = 6y - 7
x = 6 * 1 - 7
x = 6 - 7
x = -1
Hello! So in this case, what we know is that he ran 1 1/4 laps in 2 minutes. Meaning he ran 5/4 in 2 minutes. In order to figure out how many laps John ran per minute. We need to take the fraction form and divide both the numerator and the denominator and then divide it by the amount of minutes to find the average laps he makes per minute. Which in this case would be 1.25 laps per minute. We can simply take the decimal form of it and divide it by the amount of minutes to get 0.625. If you were to test out all of the options in decimal form. 5/8 would match this value.
