Answer:
-1/3x+2y=4
Step-by-step explanation:
Substitute the negative reciprocal.
-1/3x+2y=4
Nora's speed (5*8)m²/2h= 20 m²/h.
Zack's speed (4*9)m²/3h= 12 m²/h
Together for 1 h they paint (20+12) m²/h=32m²/h
Given area (10*12)m²=120 m²
120m² *1h/32m² = 3.75 h (3h 45 min) to paint 10m*12m together.
X = greater than or equal to six
Because you divide the 6 from each side
6x > 36
-----------
6. 6
Which equals x = greater than or equal to six
It has to be greater than or equal to because it had the line under it which means equal to and has the open mouth of the comparison sign facing the left which is greater than. Combine them together
