The equation that can be used to represent the ages of Sarah and his brother will be 2x - 12 = 16.
<h3>How to solve the equation</h3>
From the question given, Sarah's brother is 12 less than twice her age and Sarah is 16.
Let Sarah's age be represented by x.
Therefore, the equation to represent the situation will be:
= (2 × x) - 12 = 16
2x - 12 = 16
2x = 16 + 12.
2x = 28
x = 28/2 = 14
Sarah is 14 years.

When dividing fractions, " flip " what u r dividing by, then multiply
Examples :
(2/3) / (4/5) = 2/3 * 5/4 = 10/12 reduces to 5/6
8 / (1/5) = 8 * 5/1 = 40
(1/3) / 7 = 1/3 * 1/7 = 1/21
just make sure u " flip " the number u r dividing by and not the other one

AB = 5.65 units
AC = 5.83 units
CB = 1.41 units
Perimeter =5.65 + 5.83 + 1.41 = 12.89 units
Area = 1/2 * 1.41 * 5.65 = 3.98units
Answer:

Step-by-step explanation:
Given:
'w' represents inches of water left after 't' minutes of time.
The dripping out of water is a linear function.
At time 't' equal to 0, the bucket was empty.
After 14 minutes, there are 7 inches of water in the bucket.
A linear function model is of the form: 

Now, at 
At 
Therefore, plugging these values in the above linear model and solving the system of linear equations. This gives,

Therefore, the values of 'm' and 'b' are 0.5 and 0 respectively.
Thus, the linear model is given as:
