anonymous 3 years ago Solve. 3t < –15 (1 point) t < –5 t > –5 t < –45 t > –45

1. anonymous

divide each side by 3. t < -5

2. anonymous

can you help me with a couple more?

3. anonymous

sure!

Solve. ≥ 12 (1 point) r ≤ 48 r ≥ 3 r ≥ 48 r ≤ 3

@santw

6. anonymous

did you type that right? @SmithAshley

Solve. r/4 ≥ 12 (1 point)r ≤ 48 r ≥ 3 r ≥ 48 r ≤ 3

8. anonymous

to get rid of the /4, multiply both sides by 4. after that you have $4(\frac{r }{ 4 } \ge 12)$ the 4's cancel and leaves the 3rd option. $r \ge48$

i'm trying to make sure you get the work too!

10. anonymous

can you help me with one more please?

11. anonymous

not the third, the second! ~_~ just post em, and notify me.

Solve. –3y ≤ –18 (1 point) y ≤ –6 y ≤ 6 y ≥ 6 y ≤ 54 @santw

13. anonymous

divide each side by -3. so you get $y \le6$

14. anonymous

You only got 1 right and the other wrong :( @santw

15. anonymous

sorry! which one?

16. anonymous

number 2 and 3. Thats ok! :)

3t < -15 t < -5 is right r/4>= 12 r >= 48 is also right -3y=< -18 however isn't y=< 6 because when you divide by a negative number you have to switch the sign around to make it y>= 6. Just for anyone finding this who may be confused by "SmithAshley" saying 2 were wrong when in fact only one was wrong.
