Answer:
63 red marbles.
Step-by-step explanation:
Because the probability of drawing a red marble is 7/8, the number of red marbles = 7/8 * 72
= 7 * 9
= 63.
Answer:
6
Step-by-step explanation:
6j + 27 = j + 57
6j - j = 57 - 27
5j = 30
j = 30 / 5
j = 6
X intercept: when Y = 0
Y intercept: when X = 0
Plug into equation
4x + 6(0) = 12
4x = 12, x = 3
Therefore x int = (3,0)
4(0) + 6y = 12
6y = 12, y = 2
Therefore y int = (0,2)
Plug those points then draw a line through them
