We know that the total is 180 degrees of the lines.

To find x:
(5x+20)+(4x-11) = 180
x=19

To find y, input the value of x into the equation 4x-11 since this equation is equal to 2y+19
4(19)-11 = 65
2y+19 = 65
y=23

Answer:

5 minutes

Step-by-step explanation:

we know that

Jason runs 440 yards in 75 seconds

using proportion

Find out how many minutes does it take him to run a 1.760 yards (one mile)

$\frac{440}{75}=\frac{1,760}{x}\\\\x=1,760(75)/440\\\\x= 300\ sec$

Convert seconds to minutes

Divide by 60

$300\ sec=300/60=5\ min$
