Answer:
Arnez is 4. Andell is 13. Marianne is 7.
Step-by-step explanation:
Let x represent Arnez's age. If we write out an equation, we end up with this:
24 = (9 + x) + (x + 3) + x
24 = 9 + x + x + 3 + x
24 = (x + x + x) + (9 + 3)
24 = 3x + 12
24 - 12 = 3x + 12 - 12
12 / 3 = 3x / 3
4 = x

Answer:
1
Step-by-step explanation:
(3, -4) is on the line because the equation is point-slope equation where the point (x1, y1) is;
y - y1 = m(x- x1)
That would be 644.8 / 31 = 20.8 feet / second
