Answer:
first option
Step-by-step explanation:
Always remember to graph a diagram :)
If 4x = 8x - 1 then 4x must be equivalent to 1. So that means x is .25 or 1/4.

He needs to answer 6 mails.
Step-by-step explanation:
Given,
The number of mails = 18
Among them, he needs to answer 30% of mail.
To find the number of mails he needs to answer.
Formula
Of represents multiplication
Now,
The number of mails he needs to answer = 30% of 18
= 30% × 18
=
× 18
= 5.4
So,
He needs to answer 6 mails.
Step-by-step explanation:
believe it or not, the area of any triangle is
baseline × height / 2
we have here 2 triangles, both with the same baseline (8 cm), but with 2 different heights : 6.5 cm and 4.6 cm.
so, their areas are
8 × 6.5 / 2 = 4 × 6.5 = 26 cm²
8 × 4.6 / 2 = 4 × 4.6 = 18.4 cm²
so, in total, the shaded region is
26 + 18.4 = 44.4 cm²
