the greatest common factor is 2
Becky - x marbles;
Chris - y marbles;
Dan - z marbles
y = 2 x
z = y + 7
x + y + z = 57
--------------------
z = 2 x + 7
x + 2 x + 2 x + 7 = 57
5 x + 7 = 57
5 x = 57 - 7
5 x = 50
x = 50 : 5
x = 10, y = 20, z = 27
Answer: Dan is not correct.
I'd he happy to, But you forgot to post the question.
(6, 7) and (-3, -2)
1. Find the slope.
m = slope
m = (-2 -7)/(-3 -6)
m = -9/-9
m = 1
2. Plug the slope and one of the points into the equation y - y_1 = m(x - x_1).
y - 7 = 1(x - 6)
3. Solve for y.
y - 7 = x - 6
y = x - 6 + 7
y = x + 1
