1. Problem 40 is not provided, so we will solve problem 44: Solve the inequality $$8 - 10 > -3$$. 2. Write the inequality: $$8 - 10 > -3$$. 3. Simplify the left side: $$8 - 10 = -2$$, so the inequality becomes $$-2 > -3$$. 4. Since $$-2$$ is greater than $$-3$$, the inequality is true. 5. Therefore, the solution is all real numbers because the inequality holds true without any variable. Now, problem 48: Simplify the expression $$5(3^2 + 4) - 8t$$. 1. Calculate inside the parentheses: $$3^2 = 9$$, so $$3^2 + 4 = 9 + 4 = 13$$. 2. Multiply by 5: $$5 \times 13 = 65$$. 3. The expression becomes $$65 - 8t$$. 4. This is the simplified form. Since problem 40 is missing, only problem 44 and 48 are solved.
