We will use the followin property of logarithms:

So, we have

If you multiply both sides by 4, you get

Answer:
Step-by-step explanation:
- x = 36° as alternate interior angles are congruent
- z = 110° as opposite angles of parallelogram are congruent
- x + y + 110° = 180° as adjacent angles of parallelogram are supplementary
- y = 180° - 110° - 36° = 34°
Correct choice is C
9+10=?
9 = 3x3
10= 5x2
3 (from 3x3) x 5 (from 5x2) = 15
3 (from 3x3) x 2 (from 5x2) = 6
15+6=21
Therefore 9+10=21

Step-by-step explanation:
Answer:
The original price of an item less a discount of 20% is 0.8p where p is the original price
Step-by-step explanation:
Here, we want to write an algebraic expression that represents the original price of an item less a discount of 20%
Let the original price of the item be p
The meaning of the ‘less’ is that we are subtracting 20% of the price from the original price ;
So 20% of the price will be 20/100 * p = 20p/100 = p/5 = 0.2p
So let’s take this away from the original price p
That will be;
p - 0.2p = p(1-0.2) = 0.8p
