X+y=6
2x+y=4
solve the both
x+y=6
- (2x+y=4)
-x = 2
x=-2
substitute the value of x in x+y=6
-2+y=6
y=6+2
y=8
therefore the answer is (-2,8)
The answer to the question is 12.875
Answer:
Amber rode for 36 minutes in total.
Step-by-step explanation:
Lets create a ratio table:
Time elpased (minutes) : Laps around park
9 : 1
36 : 4
Amber rode for 36 minutes in total.
Y = 1st angle
X = 2nd angle
Y = 3X - 16
90 = X + Y
90 = X + (3X -16)
Do some algebra and X=26.5
So substitute x back in to find y, and Y=63.5
