Step-by-step explanation:
The expression to write in this problem is:
"the sum of x and 12 equals the sum of half of x and 5"
We have:
- The sum of x and 12 is:
- The sum of half of x and 5 is:
So, the equation to write in this problem is
We solve it as follows:
1) First, we subtract from both sides, and we get
2) Then, we subtract 12 from both sides:
3) Now we multiply both sides by 2:
So, this is the solution.
Answer:
(Choice A) 5M

Let total no. of e-mails in inbox be x
Since she read 80 % of mails i.e 80 % of x
⇒
⇒
⇒

⇒
⇒
⇒
⇒
⇒
⇒
Thus the expression represent the number of e-mails Danette had in her inbox before she started reading is 5M.
Hence Choice A is correct.
