Josh: Please show how you arrive at your answers. In the long run you'd get better feedback by doing so.

Answer 2

i only post the ones i have no clue on

Answer 3

sorry i was on brb

Answer 4

Are you sure that the original problem doesn't provide units of measurement with the "66" and "330?"

Answer 5

no i'm saying i DON'T KNOW

Answer 6

i'll check that out

Answer 7

i still don't get it

Answer 8

not all of us are good at math xD

Answer 9

One o the more common applications of algebra is the relationship

Distance = Rate * Time. Here, "rate" refers to speed. d = r * t.

Answer 10

Given d = r * t, solve for the rate, r.

Answer 11

...

Answer 12

what is r 330?

Answer 13

ok i see it's speed

Answer 14

but i don't see where they give that is it the 330?

Answer 15

Gave you an algebraic formula ( d = r*t ) and asked you to solve it algebraically for the rate (speed), r.

Given d = rt, solve for r, please.

Answer 16

This was your original post:

Steve drove at a constant rate to the beach for a vacation. In the equation below, t is the time in hours it took Steve to drive to the beach.

66t=330

Answer 17

Given d = r * t, solve for r.

Answer 18

yes but if ir's r * t how do i find r?

Answer 19

r anyway

Answer 20

Solve for r algebraically. That means: Isolate r.

If d = r * t, divide both sides of the equation by t. That will leave r alone on the right side.

Answer 21

i still don't get it i'm right where i started

Answer 22

d = r * t. distance equals rate times time.

Solve for the rate, r, by dividing both sides of this equation by t:

d r* t
---- = -----
t t

Cancel out the "t" on the right side, please. Your result?

Answer 23

rate = t
330=66t
since you have to make t the subject (t alone on lhs)
divide 66 on both sides
t = 330/66
t=.....?

Answer 24

but if t is the distance then what's d?

Answer 25

5

Answer 26

Faiq: Joshua needs to solve for the RATE, not for the time.

Answer 27

i have NO idea what you're talking about at all :l

Answer 28

Have you not done any preparation? Read an introductory algebra book? It's expecting a lot, perhaps too much, if you come to OpenStudy to expect people to teach you concepts from the very beginning.

Answer 29

forget it ima guess onto the next question for me

Answer 30

oh sorry t = speed
