Answer:
The number is 6
Step-by-step explanation:
Let's say that the reciprocal of the number is x
1/2 + 3 = 1
3x = 1/2
divided both sides by 3
x = 1/6
Since x is the reciprocal of the number, flip 1/6 and you will get 6/1
6/1 is really just 6 so that's your answer.
Hope this helps :)
Step-by-step explanation:
8x + x² - 2y + y² - 64 = 0
(x + 4)² + (y - 1)² - 81 = 0
(x + 4)² + (y - 1)² = 81
Hencr the center is (-4,1) and the radius is 9.
Answer:
5 seconds.
Step-by-step explanation:
Make an equation.
Time in air = x
Time in water = 12 - x
16x + 36 - 3x = 127
13x = 91
x = 7
12 - 7 = 5
