Answer:
Step-by-step explanation:
2x > 10 Divide by 2
2x/2 >10/2
x > 5
x cannot be 5 or anything smaller.
In English, x >5 reads as x must be greater than 5. (It can't be equal to 5 because 5 is not greater than 5)
The only two items that work are
8 which is greater than 5 and
30 which is also greater than 5
Answer:
117
Step-by-step explanation:
4 : 9 = 52 : 117
Since
4 : 9 = 52 : X
Then we know
9/4 = X/52
Multiplying both sides by 52 cancels on the right
52 × (9/4) = (X/52) × 52
52 × (9/4) = X
Then solving for X
X = 52 × (9/4)
X = 117
Therefore
4 : 9 = 52 : 117
Answer:
x = 7
Step-by-step explanation:
1*2*3*4*5*6*7 = 5040
x*8*9*10 = 720x
720x = 5040
720 / 5040 = 7
x = 7.
Answer:
1/25.
Step-by-step explanation:
The second roll is independent of the first so the probabilities are multuplied
Prob(rolling 2 sixes = 1/5 * 1/5
= 1/25.
Answer:
8P3 = 336
9C4 = 126
Step-by-step explanation:
8P3 = 8! ÷ 5! = 8x7x6 = 336
9C4 = 9! ÷ (5!·4!) = (9x8x7x6) ÷ (4x3x2) = 126
