5x = 2x+12 because in similar triangles, the angles are ALWAYS equal
3x=12
x=4
2(4)+12=A
A=20 degrees
The equation of the line for this question can be stated as,
What does y = when x is -1 or
What does x = when y is 2
So since the slope of the line is 2, we can assume that B and C must be the answers but since you want one answer we need to be more accurate.
The answer is C
Because when y = 0 x = -1 and when y = 2 x = 0
It would take them another 2.5 hours. To solve this you first need to multiply 60 by 4 to get 240. Subtract 240 from 780 to get 540. Then, Multiply 65 by 6 to get 390. Subtract 390 from the remaining 540 to get 150. Divide the final 150 by 60 to get 2.5. this is the remaining time they have to go before they reach their family and friends.
