Answer:
Duku is 9 meters below the surface of the water.
Step-by-step explanation:
Given:
Distance of Kojo below surface of the water = 14 meters.
Also,
Duku is 5 meters above kojo.
We need to find the Duku position relative to the surface of the water
Solution:
Now we can say that;
Distance of Duku is equal to Distance of Kojo minus 5
framing in equation form we get;
Distance of Duku = 14 - 5 =9 meters.
Hence We can say that Duku is 9 meters below the surface of the water.
Subtract 4 from 8. Then divide 20 by 4 and you get your answer for w. w=5.
Answer:
$100 prize = 15, $25 prize = 48
Step-by-step explanation:
Let,
$100 prize = x
$25 prize = y
=> x + y = 63 (1)
=> 100x + 25y = 2700 (2)
=> 100x/25 + 25y/25 = 2700/25
=> 4x + y = 108 (3)
On subtracting 2 and 3
=> 4x + y - (x + y) = 108 - 63
=> 4x + y - x - y = 45
=> 3x = 45
=> x = 15
=> 15 + y = 63
=> y = 63 - 15
=> y = 48
Answer:
x=8
this equation has double roots
x^2+16x+64=0
(x+8)(x+8)=0
