We are told that l is the length of the rectangle. We are told that the widht is 4 less than half the lenght. So, first, we calculate the half of l, which would be
the part that says "4 less than" means that we should subtract 4 from the half of length. So we get
now, this expression should be equal to the width , that we'll note as w. So we end up with the equation
To calculate percentage, we turn the percentage into a decimal.
30% of 30 = 0.3 of 30 = 0.3 x 10
0.3 x 10 = 3

Answer:
The last option of these question
Answer: x = 20
Step-by-step explanation:
So the figures are the same, except the bigger one is bigger. It's equally bigger on all sides, so basically 6 * y = 15 to find what it is enlarged by. Then multiple 8 by y to find the missing length.
6*y = 15
/6
y = 2.5
8 * 2.5 = 20
We can also check this by:
4 * 2.5 = 10
6 * 2.5 = 15
8 * 2.5 = 20
Answer:
25 = 23
100 = X
Cross multiply and you will have:
25x = 2300
