A scuba diver descends at a rate of 1/3 feet per second. How many minutes does it take her to dive from the surface to 120 feet below sea level?

6 min

Step-by-step explanation:

120 ft / ⅓ ft/s = 360 s

360 s / 60 s/min = 6 min

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

2

x+10

i think the answer is b.

step-by-step explanation:

not 100% sure though.
