Step-by-step explanation:
Answer:
Bill has 13 books. Bob has 26 books.
Step-by-step explanation:
52 divided by 2 = 26
26 divided by 2 = 13
13 x 2 = 26 and 26 + 26 = 52
Answer:
RS = 32
Step-by-step explanation:
M is the bisector of RS , then
RM = MS , that is
6x - 2 = 3x + 7 ( subtract 3x from both sides )
3x - 2 = 7 ( add 2 to both sides )
3x = 9 ( divide both sides by 3 )
x = 3
Then
RS = 6x - 2 + 3x + 7 = 9x + 5 = 9(3) + 5 = 27 + 5 = 32
Answer:

Step-by-step explanation:
we know that
To find out the corresponding setting to obtain the original from the copy, divide 100% by 72%
so

Simplify

Convert to percentage

Simplify

Convert to mixed number

Let the side length of the original square be x, then
1/4 x^2 = (x - 3)^2
x^2 = 4(x^2 - 6x + 9) = 4x^2 - 24x + 36
3x^2 - 24x + 36 = 0
3(x^2 - 8x + 12) = 0
x^2 - 8x + 12 = 0
x^2 - 2x - 6x + 12 = 0
x(x - 2) - 6(x - 2) = 0
(x - 6)(x - 2) = 0
x - 6 = 0 or x - 2 = 0
x = 6 or x = 2
but x cannot be 2 since the side length of the smaller square will be negative.
Therefore, the side length of the original square is 6 inches.
