a. f(x)= x; g(x)= x / x + 1
b. f(x)= x + 1; g(x)= 1 / x^2
c. f(x)= x^2; g(x)= x / x + 1
d. f(x)= x + 1; g(x)= x^2

What is the equation and solution for the sentence? the sum of a number and thirty-one is one hundred thirteen. write the equation as n-31=113 and subtract 31 from both sides. the answer is 82. write the equation as n+31=113 and subtract 31 from both sides. the answer is 82. write the equation as n+31=113 and add 31 to both sides. the answer is 144. write the equation as n-31=113 and add 31 to both sides. the answer is 144.

Anyone know? will mark brainliest if correct

When 142 is added to a number the result is 64 more times the number my options are 35 37 39 41
