Answer: 22
Step-by-step explanation:
Lines a and b are cut by transversal f.
Then from the given information,
[ If two parallel lines are cut by a transversal then, the alternate exterior angles are equal. ]

Hence, the value of x so that lines a and b are parallel lines cut by transversal = 22
Step-by-step explanation:
2.5 hours = 150 min
1/3 of 150 is 50 min, which means she spent 50 min on her history project = 100 min leftover
3/5 of 100 min is 60 min (1 hour) = 40 min leftover
She spent 40 min writing her essay
hope this helps <3
Answer: no solution
Step-by-step explanation: after simplifying they are parallel which means they have no solutions
160 = (10 + x) + x + 4x
160 = 6x + 10
150 = 6x
150/6 = x
x = 25
second number = x = 25
third number = 4x = 100
first number = x + 10 = 35
