I/13 x (where x is the age)
Step-by-step explanation:
Let the age in consideration is 'x' in variable
It is mentioned in the question as 1/13 the age
so, 1/13th the age be 1/13*x
hence the algebraic expression to be written as x/13 or 1/13*x
Here 1/13 is multiplied with x, the age in variable.
Let's represent the number by x.
x+5/x+11=7/10 (cross multiply) 9+5/9+11=14/20=7/10
(x+5)*10=(x+11)*7
10x+50=7x+77
10x+50-50=7x+77-50
10x=7x+27
10x-7x=27
3x=27
3x/3=27/3
x=9
therefore the number is 9

Answer:
m = 15 -6
Micha is 9
Step-by-step explanation:
If you let 'm' and 'r' stand for Micha's age and Raul's age, respectively, a literal equation can be ...
m = r -6
However, we are given the value of Raul's age, so the expression we want to evaluate is ...
m = 15 -6
To find Micha's age, we evaluate that expression:
m = 9
Micha is 9 years old.
