It would be 15 bcuz 3/4 ×15 = 11 and 1 over 4.
136.8 meter, or 137 meters
Work:
60 minutes x 24 hours =
1,440 minutes in a day
1,440 minutes x 9.5 cm =
13,680 centimeters
13,680 cm = 136.8 meters // 137
Falling at the rate of 2.5 m/s for 45 seconds, the anchor fell
(2.5 m/s) x (45 s) = 112.5 meters .
If it wound up only 40 meters underwater, then it must have fallen
(112.5 m - 40 m) = 72.5 meters
from its storage position on the big cruise ship,
before it ever reached the water.
Since it was falling at the rate of 2.5 m/s, it took
(72.5 m) / (2.5 m/s) = 29 seconds
to get down to the water surface after it started dropping.
Answer:
x= -12 and y=8
Step-by-step explanation:
Let's solve your system by substitution.
−x−y=4;x+2y=4
Step: Solve−x−y=4for x:
−x−y=4
−x−y+y=4+y(Add y to both sides)
−x=y+4
−x
−1
=
y+4
−1
(Divide both sides by -1)
x=−y−4
Step: Substitute−y−4forxinx+2y=4:
x+2y=4
−y−4+2y=4
y−4=4(Simplify both sides of the equation)
y−4+4=4+4(Add 4 to both sides)
y=8
Step: Substitute8foryinx=−y−4:
x=−y−4
x=−8−4
x=−12(Simplify both sides of the equation)
Answer:
x=−12 and y=8
