15-1/6n=1/6n-1
First, lets multiply both sides by 6 so that n is a whole number:
90-n=n-6
now you group like terms on each side, to do this you add n to each side and add 6 as well so it becomes:
96=2n
Now divide both sides by 2 so you have 'n' on one side and it is:
48=n
Hope this helps :)
Answer:
129 degrees
Step-by-step explanation:
Space from D and E = 75
Space from E and F = 54
Space from D and F = 75 + 54
=> Space from D and F = 129 degrees
Answer:
(x-1)^2 + (y-4)^2 = 5^2
Step-by-step explanation:
Using the standard equation of a circle with center at (h, k) and radius r:
(x-h)^2 + (y-k)^2 = r^2, we substitute 1 for h, 4 for k, 4 for x and 8 for y:
(4-1)^2 + (8-4)^2 = r^2, or
9 + 16 = 25 = r^2
Thus, the radius is 5
and the equation is (x-1)^2 + (y-4)^2 = 5^2. This matches the 2nd answer choice.
B since 11+11=22 and 3/7+4/7=1, 22+1=23
