So you have to decrease £30 by 20%
To do this, an easy way would be to first take away 100% from 20% because you are DECREASING :
100 - 20 = 80
Then divide your answer by 100 :
80 / 100 = 0.8
This means 0.8 is going to be your multiplier so you do
0.8 * 30 = 24
Answer = £24
I think the answer would be 4/5
Answer:
Option (B)
Step-by-step explanation:
The given question is incomplete; here is the complete question.
The radius of a circle is 6. Using π, which equation expresses the ratio of the circumference of the circle to the circle's diameter?
A) C/6 = π
B) C/12= π
C) C = 6πr
D) C = 12πr
Formula to get the circumference of the circle is,
C = 2πr = π × D
Where C = circumference of the circle
D = Diameter of the circle
By dividing with D on both the sides of the formula,

Since, diameter 'D' = 2r,



Therefore, equation given in Option (B) will be the correct expression.
6 divided by 3.79 = 1.583 gallons
Answer:
q=17
Step-by-step explanation:
5q-10=75
add 10 to both sides to cancel out -10 on the left side
5q-10+10=75+10
5q=85
divide both sides by 5 to get rid of the 5 in 5q
5q/5=85/5
resulting in:
q=17
