Given:
A bag contains 21 red marbles, 24 green marbles, and 21 blue marbles.
To find:
What color marble will you most likely choose if you choose a marble at random from the bag.
Solution:
We have,
Number of red marbles = 21
Number of green marbles = 24
Number of blue marbles = 21
Total number of marbles = 21+24+21
= 66
Now,
The number of green marbles is largest. So, the probability of getting a green marble is largest.
Therefore, you will most likely choose green marble.
X=number of students
9x+12x=630
21x=630
x=30
so for high school, a, the 9 vans carried (9*30) 270 students while the 12 buses carried (12*30)=360 students. check:270+360=630
so for high school,b.
1x+6x=252
7x=252
x=<span>36
so the 1 van carries 36 students and the 6 buses carries (6*36) 216 students. check: 216+36=252</span>
Answer:
-1.7x -3

−4.2x+3 +2.5x−6
I like to line them vertically
−4.2x+3
2.5x−6
