Final answer:
The equation is false and the value of T is approximately 3.69.
Step-by-step explanation:
The correct answer to the question is b) False.
In the equation 10T - 40 + 3T = 8, we can simplify it by combining like terms. This gives us 13T - 40 = 8. To solve for T, we can isolate T by adding 40 to both sides of the equation. This gives us 13T = 48. Finally, we divide both sides by 13 to solve for T, which gives us T = 48/13.
So, the equation is false, and the value of T is approximately 3.69. The derived value of T, approximately 3.69, doesn't satisfy the original equation, affirming the initial statement's falsity while unveiling the correct value of T.
