Answer:
1.8 ; - 14.7
Step-by-step explanation:
Evaluate the algebraic expression 1.5t -7.2 for each given value 6 ; -5
For each of values 6 and - 5 ;
Substitute the values for t in the expression ; 1.5t - 7.2
Substituting 6 for t:
1.5(6) - 7.2
9 - 7.2
= 1.8
Substituting -5 for t:
1.5(-5) - 7.2
-7.5 - 7.2
= - 14.7
