Answer 2

To evaluate the expression 3 1/8(-y + 8) - 4 3/8(y - 16) when y = -0.6, follow these steps:

Step 1: Substitute the value of y into the expression. Step 2: Perform the operations following the order of operations (PEMDAS/BODMAS).

Let's calculate it step by step:

Step 1: Substitute y = -0.6 3 1/8(-(-0.6) + 8) - 4 3/8((-0.6) - 16)

Step 2: Simplify the expressions inside the parentheses and brackets: 3 1/8(0.6 + 8) - 4 3/8(-0.6 - 16)

Step 3: Perform addition/subtraction inside the parentheses and brackets: 3 1/8(8.6) - 4 3/8(-16.6)

Step 4: Perform multiplication: 3 * 8.6 + 1/8 * 8.6 - 4 * (-16.6) - 3/8 * (-16.6)

Step 5: Perform the remaining operations: 25.8 + 1.075 - (-66.4) + 6.225

Step 6: Perform the final addition: 25.8 + 1.075 + 66.4 + 6.225

Step 7: Calculate the final result: 98.5

Therefore, when y = -0.6, the value of the expression 3 1/8(-y + 8) - 4 3/8(y - 16) is 98.5.
