Elite marathon race times improved from 5 to ~20 years, remained linear between ~20 and ~35 years, and started to increase at the age of ~35 years in a curvilinear manner with increasing age in both women and men. The sex difference in elite marathon race time increased non-linearly and was lowest at the age of ~49 years.

The sum of three numbers is 185
Fiesta28 [93]
<h3><u>The value of the first number, x, is equal to 18.</u></h3><h3><u>The value of the second number, y, is equal to 90.</u></h3><h3><u>The value of the third number, z, is equal to 77.</u></h3>

x + y + z = 185

y = 5x

z = y - 13

Because we already have a value for y, we already have a value for z. We can now solve for a value of x.

x + 5x + 5x - 13 = 185

Add 13 to both sides.

x + 5x + 5x = 198

Combine like terms.

11x = 198

Divide both sides by 11.

x = 18

Because we have a value of x, we can solve for the exact values of y and z.

y = 5(18)

y = 90


z = (90) - 13

z = 77
