system of equations that has the solution which corresponds to a point at (12, -39)
Answer:17.78
Step-by-step explanation:
there are 2.54 centimeters in an inch. simply multiply 2.54 by 7 to get 17.78
Answer:
C
Step-by-step explanation:
The VLT is true if every x value has exactly 1 y value, which is true only in answer c.
Answer: (3√5-4√2)(√125) = 75 - 20√10
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
