Answer: He bought 7 pens.
Step-by-step explanation:
21/3 = 7
We have been given the steps to solve the equation as
Step 1: 2x = 18
Step 2: x = 18 − 2
Step 3: x = 16
There is an error in step 2.
We have
x is in multiplication with 2. So in order to get rid of 2 from the left hand side, we perform opposite operation of multiplication i.e. division.
So we must divide both sides by 2.
Therefore, A is the correct option.
A) She did not divide 18 by 2.
-0.2916/-2.7
=0.108
note:the negatives cancel each other.
The value unit is 6 2/3 that is the biggest number
