The subtraction property of equality: if we subtract one side of the equation then we also must subtract from the other side of the equation.
The division property of equality: if we divide one side of the equation by a number then we also must divide the other side by the same number.
For this equation:
3 x + 5 = 26
3 x + 5 - 5 = 26 - 5 ( the Subtraction Property of Equality )
3 x = 21
3 x : 3 = 21 : 3 ( the Division Property of Equality )
x = 7
Answer: C ) The standard method for solving an equation like 3 x + 5 = 26 is to use the Subtraction Property of Equality and then the Division Property of Equality.
Answer-
<em>The inverse of 
is </em>
<u>Solution-</u>
The given function is,
We can get the inverse by interchanging he variable x and y among themselves and then separating each variables.
So in the inverse would be,
Taking log of both sides,
As,
Applying the same,
As,
Applying the same,
Therefore, the inverse of is 
.
Answer:
C
Step-by-step explanation:
Due to the fact that you are surveying more people and that those people are differentiated there will be a more representative answer rather than a biased one.
Answer:
Yes, both shampoo and water will be enough
Given that:
Number of long and short hair member who can wash their hair ; with amount of water less than 5600 litres
To check if bathroom has enough water and shampoo for 8 long haired and 7 short haired members.
L = long-haired ; S = short-haired
70L+ 60S < 5600
Check the constraint for amount of water :
70L+ 60S < 5600
L = 8 ; S = 7
70(8) + 60(7) < 5600
560 + 420 < 5600
980 < 5600
Constraint satisfied
Number of long and short hair member who can wash their hair with shampoo not more than 2.5 litres
0.02L + 0.01S ≤ 2.5
L = 8 ; S = 7
0.02(8) + 0.01(7) ≤ 2.5
0.16 + 0.07 ≤ 2.5
0.23 ≤ 2.5 (constraint satisfied).
