X = number of hours traveled
Y = Total miles on the car
Y = 60x +45 000
for 13 hours
Y = 60(13) + 45 000
Y = 45 780
Pi(x-3)^2 *(2x + 7)
= 2pi(x)^3 - 5pi(x)^2 - 24pi(x) + 63pi
Answer:
12 years
Step-by-step explanation:
Represent the mother's age by m and the son's by 4. Currently m = 36 years old.
In x years the mother will be three times as old as her son:
mother: 36 + x years old
son: 4 + x years old
The pertinent equation to solve is:
36 + x = 3(4 + x)
Performing the multiplication, we get:
36 + x = 12 + 3x, or
24 = 2x. Then x = 12.
Check: In 12 years, will the mother's age be 3 times the son's age?
Does 36 + 12 = 3(4 + 12)?
Does 48 = 48? YES
The mother will be 3 times as old as her son in 12 years from now.
