n = 1
Answer:
54 green marbles
Step-by-step explanation:
So green : transparent = 3:2
so 3+2=5 and 3*90/5 = 54 green marbles
Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
Answer:
b x 390 =339
Step-by-step explanation:
X=60° (equilateral triangle)
y=120°
Working: (360°-120°)/2
