18.00 + 8.50 + 8.50 + 8.50 + 8.50 = 52.00
So that's 4 Friends
Parallel lines have the same slope.
so to find any line, you need a set of points, and a slope.
we already have the slope, being 3.
so, use the equation
y- (y-point)/ x-(x-point)=slope.
y-6. 3
---- = ---- (make it a fraction by puttingitover 1)
x-1. 1
cross multiply.
1(y-6)=3 (x-1)
y-6=3x-3
add 6 to both sides
Final answer: Y=3x+3
20% of 36.69 is 7.338
36.69 + 7.338 = 44.02800 divided by 4 = $11.007 (rounded)
Each friend paid $11.01
Answer is 120 because all of the angles add up to 180. 180-26-34= Y
X/15=4/16 def of similar triangle by AAA
x = 60/16=5/2
