Simple equation and only requires one step to solve. Remember, a number and a variable juxtaposed means multiplications.
One step? I know. It seems more because I was slowing down the calculations for you so could understand everything happening. For someone who can do this in their sleep it would, for them, take one step.
Answer:
the option are A.
92.4%
B.
7.6%
C.
91.8%
D.
8.2%
Step-by-step explanation:
Think of it what times 61 will equal 66....
61 () = 66
(?%) = 66 /61
(?) = 1.08196
so now it gets tricky get the percentage increase correct
based on the given answer choices I'ld say it is D
% increase = (1.08196 - 1) (100) Why the subtraction of one? ?
= 8.196%
= 8.2 %
Multiplying exponents with the same base means we just have to add the exponents. We can multiply both the numerator and denominator of 1/4 by 2 to get 2/8, and adding 2/8 and 5/8, we get 7/8. So x^1/4 times x^5/8 is x^7/8.

Hope this helps!
8 - (2/x) = y (ignore these words the answer was too short lol)
