Answer:
BC×AD=K
CKD= 180-32-79= 2x +180- 5x
-> x = (-32-79) : (-3) =37
just follow the steps given in the question
Answer:
Ernie bought 96 can of soda
Step-by-step explanation:
Let one piece of the rope be x
Let the other piece of rope be x + 5
These two pieces put together will make 20 feet.
So we say:
x + (x +5) = 20
What is x? We expand the equation.
x + x + 5 = 20
x + x = 20 - 5
2x = 15
x = 7.5
The shorter piece is therefore 7.5 feet.
The longer piece is 7.5 + 5 = 12.5 feet.
112.5 seconds per lap. As you need to convert the minutes to seconds, 7 x 60 = 420 + 30 = 450
450/4 = 112.5
