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

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

Yes A would be the solution
OpenStudy (anonymous):
Since you multiplied both sides by negative 18 you must also have switched the inequality
