Question

4*1/2*(-3.5)+8*1/2-7*(-3.5)-14=

Answer 1

$4*\frac{1}{2} *(-3.5)+8*\frac{1}{2} -7*(-3.5)-14=-7+4+24.5-14=7.5$

Answer 2

Let's solve this expression step by step:

1. First, simplify the multiplication: 4 * 1/2 = 2 8 * 1/2 = 4

2. Now, rewrite the expression with the simplified values: 2 * (-3.5) + 4 - 7 * (-3.5) - 14

3. Perform the multiplications: 2 * (-3.5) = -7 7 * (-3.5) = -24.5

4. Now, substitute the values back into the expression: -7 + 4 - (-24.5) - 14

5. Simplify further: -7 + 4 + 24.5 - 14

6. Add and subtract the numbers: (-7 + 4) + (24.5 - 14) = -3 + 10.5

7. Finally, add the two values: -3 + 10.5 = 7.5

So, the result of the expression is 7.5.
