The only symbol that could make this equation true is the less than symbol, because 6 can only be less than 8.
Answer:
<h2><u><em>
x = 1</em></u></h2>
Step-by-step explanation:
3x + 2 = (2x + 13)/3
9x + 6 = 2x + 13
9x - 2x = 13 - 6
7x = 7
x = 7 : 7
x = 1
Answer:
Step-by-step explanation:
To model the elevation of each of the helicopter, the equation will be as follows respectively.
Elevation of J = 1400 - 8t
Elevation of K = 1500 - 10t
B) The helicopter elevation after 20s and 60s be realised by substituting each of the value into the equations above.
For Elevation of J = 1400 - 8t
J = 1400 - 8(20)
J = 1400-160
J = 1240ft
Also at 60s
J= 1400 - 8(60)
J = 1400-480
J = 920ft
For Elevation of K = 1500 - 10t
K = 1500- 10(20)
K = 1500-200
K= 1300ft
At 60s
K = 1500- 10(60)
K = 1500-600
K= 900ft
C) Elevation of J = Elevation of K
1400 - 8t = 1500 - 10t
Collecting like terms
1400-1500 = -10t+8t
-100 = -2t
t = -100/-2
t = 50 seconds
Elevation = 1400 - 400 = 1000 ft
