What is the solution of Negative t divided by 18 is greater than or equal to 10.? A. t ≤-180 B. t ≥ -180 C. t ≤ 180 D. t ≥ 180

OpenStudy (anonymous):

-t/18 ≥ 10 is the equation

OpenStudy (triciaal):

multiply each side by -18

OpenStudy (anonymous):

A?

OpenStudy (triciaal):

i got B let's test to check

OpenStudy (anonymous):

If you can not visualize your problem set it up \[\frac{ -t }{ 18 } \ge 10\]

OpenStudy (anonymous):

Now solve the function for "t" while obeying the rules of inequalities

OpenStudy (triciaal):

pick a number @Johnbc when you multiply by a negative does the inequality switch like when you divide?

OpenStudy (anonymous):

Since your solutions have t as a positive value you must also not forget to make yours as well and obey the rules of dividing by negative numbers within an inequality

OpenStudy (anonymous):

@triciaal Yes if it is negative

OpenStudy (anonymous):

Yes A would be the solution

OpenStudy (anonymous):

Since you multiplied both sides by negative 18 you must also have switched the inequality

OpenStudy (triciaal):

@vexus you are correct. @Johnbc thanks
