Do you feel like multiplying both sides by -5?

OpenStudy (anonymous):

And don't forget to change inequality direction when multiplying with a negative number

OpenStudy (asad786):

still need help

OpenStudy (anonymous):

How far have you gotten?

OpenStudy (asad786):

how do you multiply with thhe fraction i need to get t

OpenStudy (alexandervonhumboldt2):

multiply both sides by 5 and then flip the sign to get t>=?

OpenStudy (alexandervonhumboldt2):

as we divide by negative, we flip the sign

OpenStudy (alexandervonhumboldt2):

woops i meant t<=

OpenStudy (asad786):

t -- 5 how do you multiply it

OpenStudy (anonymous):

t - -- * 5 = - t 5

OpenStudy (anonymous):

That was left side, so you also have to do the exact same thing on right side to even it out.

OpenStudy (asad786):

-75

OpenStudy (anonymous):

-t/5 >= 15 -t/5 * 5 >= 15 * 5 -t >= 75 Can you solve it from here?

OpenStudy (asad786):

so b

OpenStudy (anonymous):

Does this -t >= 75 look like B?

OpenStudy (asad786):

kind of

OpenStudy (anonymous):

Kind of isn't right :D You need exactly

OpenStudy (anonymous):

The next step is to multiply both sides by -1, then you would get t <= 75. Notice the direction of inequality changed!

OpenStudy (asad786):

so a

OpenStudy (anonymous):

Oops, that should have been t <= -75 there, yeah that's exactly A

OpenStudy (asad786):

thx

OpenStudy (anonymous):

You get the steps?

OpenStudy (asad786):

can you help me with two more

OpenStudy (anonymous):

OpenStudy (asad786):
