Answer:
for 6 6,12,18,24,30,36,42,48 for 9 9,18,27,36,45
Step-by-step explanation:
1) first pick red 5/9 blue 4/9
2) second pick when red has been picked red now becomes 4/8, blue stays 4/8
2) Second pick when blue has been picked blue now becomes 3/8, red stays 5/8
Mind you, you only need both different colours so:
first pick red 5/9 x sec pick blue 4/8 = 20/72
and first pick blue 4/9 x sec pick red 5/8 = 20/72
add both up 20/72 + 20/72 = 40/72 = 5/9
Answer:
28mph
Step-by-step explanation:
Let the speed at which Pat drives be xmph.
Now, we know John travels 32mph faster than Pat. Hence, John's speed is (x + 32)mph
The total distance is 440 miles.
Distance = Speed × Time
The distance traveled by each of them after 5 hours is given as follws;
Pat = 5 × x = 5x miles
John = 5(x + 32) miles
Now, if we add both distances, we get the total of 440 miles.
Hence, 5x + 5(x + 32) = 440
5x + 5x + 160 = 440
10x + 160 = 440
10x = 440 - 160 = 280
10x = 280
Hence, x = 280/10 = 28mph
I honestly think it has two solutions
X=-1
X=6
The answer is C. 12 divided by 6.
