Firstly you work out 20% of 25 then subtract it.
So 20% of 25 is 5. then you do 25-5 which is 20.
Answer:

Answer: 17.25 dollars</h3>
=======================================================
Explanation:
15% of 15 = 0.15*15 = 2.25
The cost has increased by $2.25 which means the cost per kilogram is now 15+2.25 = 17.25 dollars
------------
As a slight shortcut, we can multiply the old cost (15) by the multiplier 1.15 to get the same result:
1.15*15 = 17.25
This method allows us to chain together many percentage increases, and it also allows us to include percentage decreases as well. Note how 1.15 is basically the result of 100% + 15% = 1.00+0.15 = 1.15
Answer:
10=z or z=10
Step-by-step explanation:
1) Add four to both sides
2) You should get 10=z
Answer:
x = 15°
Step-by-step explanation:
Complementary angles are two angles whose sum = 90°
∠A + ∠B = 90°
3x + 45 = 90
3x = 45
x = 45/3
x = 15°
