jason runs 440 yards in 75 seconds. At this rate, how many minutes does it take him to run a mile? (1 mile = 1,760 yards).

mamaluj [8]

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

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

Rewrite the equation of a straight line in a slope - intercept form x + 2y + 1 = 0

Liono4ka [1.6K]

Answer:

y = -x/2 -1/2

Step-by-step explanation:

$x + 2y + 1 = 0\\$

Write in the y=mx+b form

$2y =-x-1+0\\2y =-x-1$

Divide both sides by 2

$\frac{2y}{2} =\frac{-1x}{2} -\frac{1}{2} \\\\y = -\frac{x}{2} -\frac{1}{2}$
