Answer:

y = 20°

x = 35°

Explanation:

Equation's:

   1) 2y + x + 105° = 180°

   2) 3x + x + 2y = 180°

Make y subject in equation 2

3x + x + 2y = 180

4x + 2y = 180

2y = 180 - 4x

y = 90 - 2x

Insert this into equation 1

2(90 - 2x) + x + 105° = 180°

180 - 4x + x + 105 = 180

-3x = -105

x = 35°

Find value of y

y = 90 - 2x

y = 90 - 2(35)

y = 20°

Answer:I think it's 3 7.75/20 hours

Step-by-step explanation:

Multiply 2/15 by 20 (2x20 and 15x20)

Then 13/20 by 15 (13x15 and 20x15)

Subtract (195/300 - 40/300)

And you get 155/300

Then divide by 20 because dividing by 15 gives you 10.333333

So divide 155/300 by 20 (155÷20 and 300÷20)

And you get 7.75/20

Finally subtract the 2 hours from 5 hours and get 3 hours

Your answer is 3 7.75 hours
