Answer:
x = 30, z = 45, y = 105
Step-by-step explanation:
The lines are straight, so:
x = 30
z = 45
y = 180 - (45 + 30)
So there
The answer is 3km as there is 9 secs between it and distance = time/3 and 9/3 =3 so distance =3
Y= mx+c
So m= the gradient (slope)
And c=the y intercept (x,y= -3,4)
So it should be
Y=1/3x+4
Answer:
1) is equivalent multiply by 6
2) is equivalent multiply by 2 to 5/2
