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°

B:
Step-by-step explanation:

The graph below shows the velocity of two bicyclists A and B in arace from time t=0 to time t=16. The racers start side by side andtravel along the same road. The race begins at time t=0 and at timet=16 one of the racers completes the course.
It is C. Because it says that 8+ the product of 2 and a number to the third power, what it means 2×m cubed. So it is 8+2m (cubed)
41.25 because you divide the cost into the profit and that equals 41.25
