Answer:
x = 8
Step-by-step explanation:
For this question, you can use power of a point, more specifically when two secants intersect in the interior of a circle. From this, you get the equation:
(7 + x)(12) = (10)(2x + 2)
You can simplify and solve:
84 + 12x = 20x + 20
84 = 8x + 20
64 = 8x
x = 8
Answer:
x = 7
Step-by-step explanation:
=> 9/72 = 3x-20/56
=> 9×45/72 = 3x-20
=> 27/3 = x
=> x = 7
Answer:
1/16 of a mile left to walk to reach the end of the road
Step-by-step explanation:
The total distance to be walked = 15/16 miles
already walked= 7/8 miles = 14/16 miles
15/16 - 14/16 = 1/16 miles
Answer:
f(4) = 85 1/3 or 85.333...
Step-by-step explanation:
To find f(4), you must substitute 4 in place of x whenever x appears:
f(x) =
*
f(4) =
* 
Next, simplify the exponent:
f(4) =
* 256
Finally, multiply:
f(4) = 85 1/3 or 85.333...
