Claire can run 20 miles in 95 minutes. How many miles can she run in 285 minutes? A) 60 miles
B) 6.7 miles
C) 1, 353 miles
D) 190 miles

60 miles

Step-by-step explanation:

95 min is the same as 1.583 hours, you use that and do 20/1.583 to get the amount of miles Claire runs per hour. Then you divide 285 by 60 to get how many hours that is, and then you multiply the miles an hour she can run by how many hours 285 minutes is. Hope this helped, it wasn't the best explanation though.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
