Question

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

Answer 1

divide each side by 3.
t < -5

Answer 2

can you help me with a couple more?

Answer 3

sure!

Answer 4

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

Answer 5

@santw

Answer 6

did you type that right? @SmithAshley

Answer 7

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

Answer 8

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.
\[r \ge48\]

Answer 9

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

Answer 10

can you help me with one more please?

Answer 11

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

Answer 12

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

Answer 13

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

Answer 14

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

Answer 15

sorry! which one?

Answer 16

number 2 and 3. Thats ok! :)

Answer 17

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.
