Step-by-step explanation:
Age of dave = y
Age of Julia = x
y = 4x - 8
if y = 16
then
4x - 8 = 16
4x = 16 + 8
4x = 24
x = 24/4
x = 6
Julia is 6 years old
The formula of the present value of annuity ordinary is
Pv=pmt [(1-(1+r/k)^(-kn))÷( r/k)]
Pv present value?
PMT monthly payment 425
R interest rate 0.055
K compounded monthly 12
T time 1 year
Pv=425×((1−(1+0.055÷12)^(
−12))÷(0.055÷12))
=4,951.26
20/3 - Take the 6 2/3, multiply the 6 and the 3 (6 x 3 = 18), then add the 2 (18 + 2 = 20). Put that number over the original 3 and you've got yourself a mixed number.

Pythagorean theorem
x^2 + 5^2 = 10^2
x^2 + 25 = 100
x^2 = 75
x = +sqrt(75), -sqrt(75) = +5sqrt(3), -5sqrt(3)
