Answer 2

To solve the expression -9.72 + b + 7.4 + 5.72 + (-7.2) when b = 3 14/17, you need to substitute the value of b into the expression and then perform the arithmetic operations. Let's do the calculations step by step:

b = 3 14/17 Convert the mixed fraction b to a decimal: b = 3 + 14/17 = 3 + 0.8235294117647058 ≈ 3.82353

Now, let's substitute b in the expression:

-9.72 + b + 7.4 + 5.72 + (-7.2) = -9.72 + 3.82353 + 7.4 + 5.72 - 7.2 = (combine like terms) = -9.72 + 12.34353 - 7.2 = (combine like terms) = -4.57647

So, the value of the expression when b = 3 14/17 is approximately -4.57647.
