Add 21 to both sides, so you get 9z = 81
Answer:
273 = 3 x 7 x 13.
273 is 100010001 in base 2 (binary), 333 in base 9, and 111 in base 16.
The 273rd prime minus the sum of gaps between the first 273 consecutive primes minus 1 equals 273.
273 is the sum of each of two consecutive sums of consecutive numbers: 273 = 36 + 37 + 38 + 39 + 40 + 41 + 42 = 43 + 44 + 45 + 46 + 47 + 48.
Answer:
x = 41
Step-by-step explanation:
By the Angle Bisector Theorem, which basically states that EG / GD = EH / DH, we get this: 49 / 35 = 58.8 / (x + 1). Now, if we simplify, we get 7/5 = 58.8 / (x + 1). Cross-multiply to get 294 = 7x + 7, or 7x = 287. From here, it is obvious that x = 41.
Answer:
B) 4
Step-by-step explanation:
(f-g)(x) = x² - 4x - 1
5² - 4(5) - 1 = 4
Answer:
n = 11/3
Step-by-step explanation:
n = certain number
6n - 1 = 21
6n = 22
n = 22/6 or 11/3
