Olivia's work and solution to the equation -6x + 11=43 is shown. identify each error in olivia, s work ad epxplian what she would have done instead.
-6x + 11=43
+11 +11
-6x = 54
-6x/6 = 54/6
x = 9

The correct solution algorithm for the equation -6x + 11 = 43 is give as follows:

-6x + 11 = 43

Subtract 11 from both sides to get:
-6x + 11 - 11 = 43 - 11
-6x = 32

Divide both sides by -6 to get:
-6x / -6 = 32 / -6
x = -5.33

Given Olivia's work as follows:

-6x + 11= 43
+11 +11
-6x = 54
-6x/6 = 54/6
X = 9

Therefore, Olivia's errors are:
1) She added 11 instead of subtracting 11.
2) She divided by 6 instead of -6.

One unique triangle, because those angles add up to 180, and that's how many degrees there are in one triangle.

Ithink you're supposed to multiply 12.50 which is how much he makes per hour and then multiply it by each number then add whats left togrther and there's your answer
