Question

In which step below does a mistake first appear in simplifying the expression
0.5 (-12 + 6) - 3(c + 4) + 10(c - 5)?
Step One: -6c + 3 - 3(c +4) + 10(c - 5)
Step Two: -6c + 3 - 3c - 12 + 10(c - 5)
Step Three: -6c + 3 - 3c - 12 + 10c - 50
Step Four: 7c - 41
A: Step 1
B: Step 2
C: Step 3
D: Step 4

Answer 1

0.5(-12 + 6) - 3(c + 4) + 10(c - 5)

0.5(-6) - 3(c + 4) + 10(c - 5)
-3 - 3(c + 4) + 10(c - 5)

Is this problem correctly written ?

Answer 2

Is it supposed to be : 0.5(-12c + 6) - 3(c + 4) + 10(c - 5) ??

Answer 3

yeahh.

Answer 4

0.5(-12c + 6) - 3(c + 4) + 10(c - 5)
-6c + 3 - 3(c + 4) + 10(c - 5) step 1 is correct
-6c + 3 - 3c - 12 + 10(c - 5) step 2 is correct
-6c + 3 - 3c - 12 + 10c - 50 step 3 is correct
c - 59 step 4 is incorrect

Answer 5

Okay. Thank you(:
