in a triathlon, jenny swam for 1 hour biked for 1.75 hours and ran for 1 hour. her average biking speed was 2 times her average running speed and her average running speed was 8 times her average swimming speed the total distance of the triathlon was 55.5 kilometers write an equation and solve it to find jenny's average speed in kilometers per hour. explain your solution path and the reasoning behind your work

the first question mark is 6 and the second question mark is 26 (the square root)

step-by-step explanation:

the correct is answer is a 9-sided polygon!

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
