Answer:
49/4 or 12.25
Step-by-step explanation:
+ We replace y= 6 and z= 3 into this expression: 3/2y-3+5\3 z
+ We find that: 
The answer is 49/4 or 12.25

Answer:
JL = 62 (units)
Step-by-step explanation:
OK, Here we can use the part whole postulates theorem to assist us:
JL consists of parts JK + KL such that, through substitution,
5x + 2 = 27 + ( 3x - 1 )
Here we can solve for x to determine 5x + 2, and thus the value of JL:
5x + 2 = 27 + 3x - 1
2x + 2 = 27 - 1
2x + 2 = 26
2x = 24
x = 12
Substitute the value of x for 5x + 2, to get JL:
JL = 5 (12) + 2
JL = 60 + 2
JL = 62 (units)
Answer:
distance = 1.5 miles(approx.)
Step-by-step explanation:
given,
speed of sound = 1130 ft/s
1 ft = 0.3048
1130 ft/s = 0.3048 × 1130 m/s
= 344.424 m/s
time = 7 second
distance = speed × time
distance = 344.424 × 7
distance = 2410.968 m
1 m = 0.0006214 miles
2410.968 m = (0.0006214 × 2410.968) miles
distance = 1.498 miles
distance = 1.5 miles(approx.)
The rate of the airplane is 300mph per hour.
