5. If we represent the length of a line by a,
how may we represent the length of a
line that is 3 inches longer? If the com-
bined length of the two lines is 15 inches,
what is the length of each line?

Respuesta :

Answer:

Step-by-step explanation:Let a be the length of line

from question we know that

a+3 is another line

Here

a+(a+3)=15. ( Given in question )

2a = 15 -3

2a=12

a=12/2

a=6

Here a and a +3 are the length of the line

Finally ,6 and 9 are the lengths
