Answer:
(Choice A) 5M
Step-by-step explanation:
Let total no. of e-mails in inbox be x
Since she read 80 % of mails i.e 80 % of x
⇒
⇒
⇒
So, she read 0.8x e-mails.
So, remaining email = total e-mails - read e-mails
Since we are given that Danette still has M unread e-mails.
⇒
⇒

⇒
⇒
⇒
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.
If the triangles are similar, the proportion of the legs on the left to the legs on the right will be equal. This proportion would look like:
(You needed to combine the orange segment and the yellow segment to find the total length of the large triangle).
Now, cross multiply and solve for x:
28x+14=30x
<em>*Subtract 28x from both sides to isolate the variable*</em>
14=2x
<em>*Divide both sides by 2*</em>
7=x
