Answer:
s = 2q + 3
Step-by-step explanation:
A linear function has the form:
● y = mx + b
● y is the output of the function
● x is the variabke that we input
● b is the y-intetcept.
Focus on y and x.
Notice that y depends of the value of x. The value of y changes by changing x. So the value of x controls the output y.
y is dependent but x is not.

● 6q = 3s - 9
We want q to be the independent variable wich means that q will be the input. Therefore s should be the output.
The strategy we are going to follow is separating s in one side alone.
● 6q = 3s - 9
Add 9 to both sides
● 6q + 9 = 3s -9 + 9
● 6q + 9 = 3s
Divide both sides by 3
● (6q + 9)/3 = (3s)/3
● (6q)/3 + 9/3 = s
● s = 2q + 3
So the answer is s = 2q + 3
Given :
Nathan smiled at 50 people one day and recorded that 36 people smiled back at him.
To Find :
How many people should Nathan expect to return a smile if he smiles at 650 people over a period of time.
Solution :
Ratio of people smiled by total number of people is :

Now, it is given that we have to use the given conditions.
Therefore, ratio will be same :

Therefore, number of smiles Nathan expect to return is 468.

Answer:
solution for n is 
Step-by-step explanation:
Given an equation containing one variable n.
The equation is as follows:

To solve for n we can subtract 3/4 from both the sides
The result is

Verify:
Substitute the answer in the given equation.

Both sides equal thus proving our correctness of answer.
Answer:
C: 70 Mins
Step-by-step explanation:
1, 20ft*15ft=300ft^2
2, 30ft*25ft=750ft^2
3, 750ft-350ft=450ft^2
4, 450 ft^2 = 30 mins
5, 350ft=750ft=1050ft^2
6, 1050/450=2.3333
7, 30*2.3333=70
8, 70 mins
