=

Hence, They had travelled 6% of the total trip when Alexandra fell asleep.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

answer: 457.14

step-by-step explanation:

205 - 45 = 160

160 / .35 = 457.142857
