Answer:
The answer is 27t - 12.
Step-by-step explanation:
1) Remove parentheses.
[tex] \frac{1}{2} \times 18t + 2t \times 9 - 12[/tex]
2) Use this rule: a/b × c/d = ac/bd.
[tex] \frac{1 \times 18t}{2} + 2t \times 9 - 12[/tex]
3) Simplify 1 × 18t to 18t.
[tex] \frac{18t}{2} + 2t \times 9 - 12[/tex]
4) Simplify 18t/2 to 9t.
[tex]9t + 2t \times 9 - 12[/tex]
5) Simplify 2t × 9 to 18t.
[tex]9t + 18t - 12[/tex]
6) Collect like terms.
[tex](9t + 18t) - 12[/tex]
7) Simplify.
[tex]27t - 12[/tex]
Thus, the answer is 27t - 12.
