An airplane is flying at an altitude of 28,000 feet. It descends for 7 minutes to an altitude of 15,050 feet. If the aircraft continues at the same rate of descent, approximately how many minutes until the aircraft lands? please give an explanation!

28,000-15,050=12,950   12,950/7=1,850    15,050/1,850= 8       (8minutes)

Step-by-step explanation:

Brainlist please

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
