Please help! 25 point question!!!
Consider the following expression.



The expression is evaluated below, but a mistake is made in the calculation somewhere. Identify the mistake and then evaluate the expression correctly. Complete the statements below.



The mistake occurs in step __________ (1,2,3,4, or 5)
because the student evaluated _________
a. (-11.7 + 0.5)
b. (27.4 - 32.2)
c.(1 - (-1))
d. (2.2 + (-11.2))
e.(-9 - (-4.8))
f. -4.2


The correct solution is _________.
a. -4.1
b. -2.2
c. -6.2
d. -4.4
e -2

Answer 1

Answer:

The mistake happened in Step 2: (1 - (-1)) does not equal 0, it equals 2. (1 - (-1)) is equivalent to 1 + 1, which equals 2.

Step-by-step explanation:

So,

The mistake occurs in step 2, because the student evaluated step c. (1 - (-1)) incorrectly. The correct solution is 2.

Edit: The correct solution to the equation is -2.2. I though when it was asking the correct solution, it was asking for the correction to the mistake made. The solution to the equation is -2.2, but the solution to the mistake made is 2.

I hope this helps!
