Step-by-step explanation:
The question is not properly structured but we can as well find the sum of 5/7 and 10 as shown;
Hence the expression written in equivalent form of common denominator is 
The sum is 
Subtract the powers
c. 9-7 so 10^2
d. 8-1 so 5^7

? is there a option?
Step-by-step explanation:
Easy! multiply the 6% by $8 then add it to the $8, now, multiply the 15% by the total of the cost with tax. then you all that to the total. ($9.75)
Answer:
Let x represent the number from the sentence.
Step-by-step explanation:
2(x) + 2(1/x) = 20/3
2x + 2/x = 20/3
multiply both sides of the equation by 3x
6x + 6 = 20x
6x - 20x + 6 = 0
6x - 18x - 2x + 6 = 0
6x(x-3 -2(x-3) = 0
(6x-2 = 0 or x-3 = 0
6x = 2 or x = 3
x = 2/6
x = 1/3
Since x represented the number
Therefore x = 1/3 or 3
