I hope this helps you
-x+4=2x+1
4-1=2x+x
3=3x
x=1
y=-1+4
y=3
Answer:
20 in³
Step-by-step explanation:
Volume of 300 pages:
10 × 8 × 3/4
When the no. of pages change, only the thickness of the book changes:
Volume = 10 × 8 × ¼
= 20 in³
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
