If we multiply or divide both sides of an inequality by a negative number, you have to flip the inequality. Hope this helps :)
Answer:
Step-by-step explanation:
If she had two dice, a seven is the most common roll you can get, although the odds are still against you.
To get a seven with just 1 die is impossible.
V = x/t = 4.5 mil / 3 h = 1.5 mph
Since, v = 1.5 mph (or we can say that v is constant), distance and time vary directly and the constant of variation is 1.5 mph.
For the first one it's 90.5, I know cause I just took the test and it's right. The second one I'm not sure..
9!/(8!*(9-8)!)=9
or just use a calculator and use the nCr function
