The answer is 9.
1/5 of 30 is 6.
1/2 of 30 is 15
If you add 6+15=21
And then 30-21=9
So I believe the answer is 9! Hope this helps!! <3
Answer:
2
Step-by-step explanation:
A midpoint divides a segment in two equal segments
DB = 3t
AB = 6t
BE = 4t
BC = 8t
8t + 6t + 7t + 6 = 48
21t = 42
t = 2
Answer:
5
Step-by-step explanation:
We are being asked in how many ways an enumerated ball can be removed without any type of replacement, therefore it would be a combination without repetition:
nCr = n! / r! * (n-r)!
n, total number of balls, 5
r, specific number of balls, 1
5C1 = 5! / (1! * 4!) = 5
Therefore there are 5 ways to do the above.
A proper fraction is when the numerator is smaller then the denominator .
so ur answer is 3/4
** fractions are improper if the numerator is bigger then the denominator.
and when the numerator and denominator are the same, the fraction equals 1
3(-1) + 9= -3 + 9= 6 that's the answer
