Jessica runs a shop that rents canoes and bicycles. Last week, she rented canoes and bicycles for a total of 140 hours. The rental cost for each canoe is $24 per hour, and the rental cost for each bicylce is $8 per hour. Jessica earned a total of $1632 last week from renting canoes for x hours and bicycles for y hours. Write two equations in terms of x and y Jessica could use to determine how many total hours she rented canoes.

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)

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.
