John and Alan have a collection of x baseball cards. John has x4 cards. What fraction of the cards does Alan have?

1 answer:

8 0

Number of cards of John: J
Number of cards of Alan: A

John and Alan have a collection of x baseball cards:
J+A=x (1)

John has x/4 cards:
J=x/4

What fraction of the cards does Alan have?

Replacing J by x/4 in the equation (1)
(1) J+A=x
x/4+A=x

Solving for A:
x/4+A-x/4=x-x/4
A=4x/4-x/4
A=(4x-x)/4
A=3x/4

Answer: Alan has 3/4 of the cards

Points B and B' have symmetry with respect to P. Find the coordinates of P when B is (2, 8) and B' is (2, 2). A. (2, 5) B. (0, 5

Alecsey [184]

Answer:

A. (2, 5)

Step-by-step explanation:

If B and B' have symmetry, then P is a midpoint between those points. We can determinate the location of point P by using the midpoint equation, whose vectorial form is:

$P(x,y) = \frac{1}{2}\cdot B(x,y)+\frac{1}{2}\cdot B'(x,y)$ (Eq. 1)
