Step-by-step explanation:
The probability of not selecting green or yellow marble is equal to the probability of selecting red and blue marble
n(S) =17
n(A)=5 (red)
n(B)=6 (blue)
answer is 5+6/17
=11/17
Answer:
the answer is an equal sign
95x=85x+288
You could add 288 to any side, it just shows that they're 288 miles apart.
Let's subtract 85x from both sides.
10x=288
28.8=x
It'll take 28.8 hours for the trains to meet. Let's make sure.
28.8×95
2,736
28.8×85
2,448
2,736-2,448
288
So, they'll meet up after 28.8 miles.
Answer:
3x = 18
x = 6
Step-by-step explanation:
Let's assume x is the variable. There are 3 pairs of pants, hence the 3. The total fee is 18, hence the 18.
Answer:
234
Step-by-step explanation:
So what we know is that
5x+9x= students
This equation is saying that for every 5 boys there are 9 girls
we can then plug in 364 for the number of students and add like terms
This means that 14x=364
this means that x=26
This means that there are 26 sets of 5 boys and 9 girls
this means that there are
130 boys
234 girls
