X/5 when x=30 is 30/5 which is 6
3y^2 when y=2 is 3(2)^2 which is 3(4) which is 12
And z=-2... if we plug these into the original question we get 6+12-(-2)
The negatives cancel and it becomes 6+12+2 which =20
Your answer is 20
Answer:
15 I think
Step-by-step explanation:
He will earn $455 of interest in one year
because 1000 x 8.5% = 85

85 + 370 = 455
Answer:
Yellow.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes. Experimental probability is found taking into account previous experiments.
In this question:
6 + 5 + 4 + 10 = 25 total marbles.
The experimental probabilities are:
6/25 probability it is red.
5/25 = 1/5 probability it is yellow. Thus, the answer is yellow.
4/25 probability it is blue.
10/25 = 2/5 probability it is green.
