Answer:
K=-2
Step-by-step explanation:
-3 = 5k + 7
Subtract 7 to the other side
-3 -7 = 5k
-10 = 5k
-2 = k
5,10,15,20,25,30,35,40,45,50,55,60,65,70,75,80,85,90,95,100
Answer:
Step-by-step explanation:
2/3 x - 4 = - 92
add 4 to both sides
2/3 x = - 88
multiply both sides by 3
2 x = - 264
divide both sides by 2
this is ur answer
Good luck

A represents the speed of the aircraft.
b represents the speed of the bus.
a=2b-5
114/b=218/a
Substitution method
114/b=218/(2b-5)
(2b-5)*(114/b)= 218
(228b-570)/b = 218
228b-570= 218b
228b-218b=570
10b= 570
b=57
Plug the value of b into one of the original equations.
a=2(57)-5
a=114-5
a=109
Final answer:
Average speed of plane= 109
Average speed of bus= 57
