One day last summer, Jim went kayaking on the Little Susitna River in Alaska. Paddling upstream against the current, he traveled

miv72 [106K]

Answer:

6.5 miles per hour

Step-by-step explanation:

At first, Jim was paddling against the current for 3 hours. Then, he paddled for 1 hour with the help of the current.

Let x be Jim's rate without the current and y be the rate of the current:

$(x-y)*3=12\\(x+y)*1=17$

By solving the linear system, we can find the rate of the current y:

$x=17-y\\(17-y-y)*3=12\\y=\frac{39}{6}\\y=6.5\ \frac{miles}{hour}$

The current has a rate of 6.5 miles per hour.

Which ordered pair is a solution of y = x + 12? (–12, –24) (0, –12) (9, 21) (24, 12)

Leto [7]

Answer:

(9,21)

Step-by-step explanation:

If you plug in all the pairs, the only one that is true is (9,21).

y=x+12

21=9+12

The above equation is true, and that is why (9,21) is the answer.

Hope this helped! :)
