Step-by-step explanation:
Givens
P is (2,8)
Q is (-6,-6)
Equation
Midpoint = (x1 + x2)/2,(y1 + y2)/2
Solution
x1 = - 6
x2 = 2
y1 = -6
y2 = 8
M = (-6 + 2)/2, (-6+8)/2
M = -4/2, 2/2
M = -2 , 1
Just to make sure that you know that the answer is reasonable, I've put the midpoint (-2,1) on a graph with the two endpoints. You could print the points out and check it with a ruler.
Answer:
They have 48 cards.
Step-by-step explanation:
let s be the number of Shauntay's cards and j be the number of Jessica's cards.
The ratio of Shauntay's cards to Jessica's cards is 5 to 3, then
(1) =
After Shauntay gives Jessica 12 of her cards, both girls have the same number of cards, then
(2) s-12 =j+12.
From (2), we get s= j+24. If we put j+24 instead of s in (1) we get:
=
3×j+24×3 = 5×j From this we get;
2×j=72 and j=36
After Shauntay gives Jessica 12 of her cards, Shauntay and Jessica would have 48 cards.
