Answer:
x = 7.416666667
Set everything equal to 180 (the total # of degrees in a triangle)
180 = 14x-13 + 4x+13 + 6x+2
Combine the variables
180 = 24x - 13 + 13 + 2
Do the math
180 = 24x +2
178 = 24x
x = 7.416666667
Step-by-step explanation:
In the 1st question
Total boxes = 6
Shaded boxes = 2
Probability = 2/6 = 1/3
It will take 3 laps. 90*35=3150 1000 m = 1 km
1 hours is equal to 60 minutes.
2 hours = 120 minutes
40% is 120 minutes = 120*40/100 = 48 minutes
