Challenge. a daughter is 28 years younger than her father. in 5 years, the father will be 3 times as old as his daughter. how old is each now?

Daughter is 9

Father is 37

Step-by-step explanation:

d= Daughter age

f= Father age

f =d+28

f+5=3(d+5) ---»» f= 3d+10

//put d+28 instead f// d + 28=3d + 10

2d = 18 --»» d=9

f = d+28 -»» f = 37

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
