<u>Answer:</u>
- The solution to the equation is 4.
<u>Step-by-step explanation:</u>
<u>Work:</u>
- 6x - 3 = 21
- => 6x = 21 + 3
- => 6x = 24
- => x = 4
Hence, <u>the solution to the equation is 4.</u>

Hey There!
In order to simplify this expression, you would have to combine the like terms. 
9+1 = 10
Nothing else could be done, therefore the answer would be.
7v + 10

That both (along with the mean) help the data be described the data's spread, which can be the slope if only two points.
        
             
        
        
        
Answer:
y = 0.2x + 37
Step-by-step explanation:
A) Find an equation in the form y = mx + b, where x is the number of monthly minutes used and y is the total monthly of the Ringular plan.
(x, y) = (minutes, cost)
(110, 59)
(600, 157)
slope = m = dy/dx
dy/dx = change in y/change in x
m = dy/dx
m = (157 - 59)/(600-110)
m = 98/490
m = 0.2
a) the linear equation:
y - 59 = 0.2(x - 110)
y - 59 = 0.2x - 22 
y = 0.2x - 22 + 59
y = 0.2x + 37
