Step-by-step explanation:
do 3 divided by 25 and you will get the percentage.
3/25 = 0.12 move the decimal over 2 plaves and boom you got it
Answer:
A
Step-by-step explanation:
-7+3(-4e-3)
-7-12e-9
-16-12e
simplify
-4(3e+4)
We're looking for 
such that
Multiplying both sides by 
gives us
Notice that when 
, the term involving 
vanishes and we're left with
Then
so that
x = 56°
Solution:
Part A:
Given data:
2x and 68° are adjacent angles in a straight line and their measures have sum of 180°.
Part B:
<em>Sum of the adjacent angles in the straight line is 180°.</em>
2x + 68° = 180°
Subtract 68° from 180°, we get
⇒ 2x = 112°
Divide by 2 on both sides, we get
⇒ x = 56°
The value of x is 56°.
Part C:
By part A and part B,
2x° + 68° = 2(56°) + 68°
= 112° + 68°
= 180°
2x° + 68° = 180°
Hence proved.
