Answer:
#11: last option is answer
#12: first option is answer
Step-by-step explanation:
#11) 5x + 6 ≤ 11
5x ≤ 5
x ≤ 1 to graph this you need a solid dot on 1 and shading to the left
#12) 5p+ 4 > 14
5p > 10
p > 2 to graph this you need an open dot on 2 and shading to the right
Answer:
11. 5x + 6 <= 11.
12. 5p + 4 > 14.
Step-by-step explanation:
11. THE GRAPH shows that x <= 1.
So it is 5x + 6 <= 11 because
5x <= 5
x <= 1.
12. THE GRAPH shows that p > 2.
So it is 5p + 4 > 14.
5p + 4 > 14
5p > 10
p > 2.

Speed = distance/time
distance = speed * time
let x = time covered by running
15 = run distance + walk distance
15 = 9(x) + 3(3-x)
15 = 9x + 9 - 3x
15 - 9 = 6x
6 = 6x
x = 1 hour
Therefore:
Running distance = speed * time
RD = 9km/hr * 1 hr
RD = 9km
