To find the weight of a brick and a half, we need to determine the weight of a single brick first.
According to the given information, a brick weighs the same as a 9-pound rock plus half of another brick. Let's denote the weight of a brick as 'B'.
Now, we can create an equation from the given information:
B = 9 + (1/2)B
To solve this equation, we can start by multiplying both sides by 2 to eliminate the fraction:
2B = 18 + B
Next, we can subtract B from both sides to isolate the B term:
2B - B = 18
Simplifying the equation, we get:
B = 18
Therefore, a single brick weighs 18 pounds.
Now, we can find the weight of a brick and a half by adding 1.5 times the weight of a brick:
Weight of brick and a half = 1.5 * Weight of a single brick
= 1.5 * 18
= 27
Therefore, a brick and a half would weigh 27 pounds.
