Step-by-step explanation:
Answer: The answer is 10(10)−3(10)−2/4+5=149/2 (Decimal: 74.5)
Step-by-step explanation: Too lazy to explain sorry sksksksksksk but like there's the answer :)
Answer:
a/(bxy) if b≠0, x≠0, y≠0, x≠y
Step-by-step explanation:
You have correctly simplified the expression. The conditions placed on both the original and simplified forms are that none of the denominator factors may be zero. The denominator factors are b, x, y, and (x-y).
Answer:
3(x + 2)(x - 6) = 0
Step-by-step explanation:
We see that if x + 2 = o then x= -2
and if x - 6 = 0, x = 6.
Answer:
10
Step-by-step explanation:
The number of tiles in the design is 1 + 2 + 3 + ...
We can model this as an arithmetic series, where the first term is 1 and the common difference is 1. The sum of the first n terms of an arithmetic series is:
S = n/2 (2a₁ + d (n − 1))
Given that a₁ = 1 and d = 1:
S = n/2 (2(1) + n − 1)
S = n/2 (n + 1)
Since S ≤ 60:
n/2 (n + 1) ≤ 60
n (n + 1) ≤ 120
n must be an integer, so from trial and error:
n ≤ 10
Mr. Tong should use 10 tiles in the final row to use the most tiles possible.
