Answer:
y = 2 / (r/3 - s/5)
Step-by-step explanation:
r/3 - 2/y = s/5
add 2/y to both sides
r/3 = s/5 + 2/y
Subtract s/5 from both sides
r/3 - s/5 = 2/y
multiply both sides by y
y(r/3 - s/5) = 2
Divide both sides by r/3 - s/5
y = 2 / (r/3 - s/5)
Parallel never cross
perpendicular is a 90 degree angle
its neither if its not 90 degree or never crossing

1.16-1.11=0.05
Answer:
Step-by-step explanation:
Give the ratio of red to green to blue marbles to be 3:5:7
Total ratio = 3+5+7 = 15
Total marbles = 600marbles
Amount of red = ratio of red/total ratio × 600
Amount of red marbles = 3/15 × 600
Amount of red marbles = 3×40 = 120marbles
Amount of green marbles = 5/15×600
Amount of green marbles = 5×40 = 200marbles
Amount of blue marbles = 7/15×600
Amount of blue marbles = 7×40 = 280marbles
