4x - 2x + 8 = 6(x + 4) Given
(4x - 2x) + 8 = 6(x + 4)
2x + 8 = 6(x + 4) Combine like terms
2x + 8 = (6)(x) + (6)(4)
2x + 8 = 6x + 24 Distributive Property
2x - 6x + 8 = 6x - 6x + 24
-4x + 8 = 24 Subtraction Property of Equality
-4x + 8 - 8 = 24 - 8
-4x = 16 Subtraction Property of Equality
-4x : (-4) = 16 : (-4)
x = -4 Division Property of Equality
Answer:
Therefore the diameter of the hole is
m.
Step-by-step explanation:
Bernoulli's equation,

P₁ = P₂= atmospheric presser
= density
[since P₁ = P₂]



[
]
Here 


Here g= 9.8 m/s² , h = 10.4 m
The velocity of water that leaves from the hole
=
m/s
=14.28 m/s.
Given, the rate of flow from the leak is

Let the diameter of the hole be d.
Then the cross section area of the hole is 
We know that,
The rate of flow = Cross section area × speed



Therefore the diameter of the hole is
m.

Answer:
1537pounds
Step-by-step explanation:
Given parameters:
Weight of baby at birth = 7.25 pounds
Unknown:
Weight at the end of 8months = ?
Solution:
From the second sentence;
Weight at the end of the eighth month = 212 x weight at birth.
Input the parameters and solve;
Weight at the end of eighth month = 212 x 7.25 = 1537pounds
