First, we translate the information that the question gives us:20+x is "twenty added to a certain number"(20+x)/5 is "the sum divided by five"1+12x is "one more than twelve times the original number"Putting it all together, we get the following equation:(x+20)/5 = 1 + 12xSolve for x:x+20=5(1+12x)x+20=5+60x20-5=60x-x15=59x15/59 = xTherefore, the original number was 15/59

Answer: m = 7
Answer:
32/243
Step-by-step explanation:
do 2 to the 5th and put it above 3 to the 5th
Rewrite 512x^3 as (8x)^3
(8x)^3 + 2197y^3
Rewrite 2197y^3 as (13y)^3
(8x)^3 + (13y)^3
Since both terms are perfect cubes, factor using the sum of cubes formula.
a^3 + b^3 = (a + b)(a^2 - ab + b^2) where a = 8x and b = 13y.
(8x + 13y)((8x)^2 - (8x)(13y) + (13y)^2)
Simplify
(8x + 13y)(64x^2 - 104xy + 169y^2)
