slega [8]

Answer: Mom = 33 Son = 11

Step-by-step explanation:

A mother is three times as old as her son

Mom age =3x

AFTER 11 YEARS:

Son’s age =x+11

Mom’s age =3x+11

Also, she will be just twice his age

3x+11 = 2*(x+11)

or,3x+ 11 = 2x +22

or,3x-2x= 22–11

or, x=11

Son’s age = 11 years and mom’s age = 33 years

the average length of string a and string d is 10x cm . the average length of string b and string c is 8x cm . the average lengt

klasskru [66]

Answer:

a= 18x

Step-by-step explanation:

(a+d)/2 = 10x (1)

(b +c)/2 = 8x (2)

(b+c+d)/3 = 6x (3)

From the equation 2, we have (b+c)= 8x *2 = 16x

From the equation 3, we have d= 6x*3 - (b+c)= 18x- 16x = 2x

From the equation 1, we have a= 10x*2 -d= 20x - 2x= 18x
