20 total marbles....7 are green
probability on first draw is 7/20...and since the marble was not replaced, the probability on the second draw is 6/19. And since they cant happen at the same time, we multiply
7/20 * 6/19 = 42/380 which reduces to 21/190
Step-by-step explanation:
diameter = 3ft
radius = 3/2 ft
perimeter of semicircle= πr = π (3/2) = 3.14×3/2
= 4.71 ft
2a²b³ and -4a²b³ are like terms as they both have the same variables with the same degrees.
Your final answer is a. True.
2x - 3 > 11 - 5x |add 3 to both sides
2x > 14 - 5x |add 5x to both sides
7x > 14 |divide both sides by 7
x > 2
x = 4
