20×+4=4(5x+1) how many solution are in this equation
Answers
Simplify both sides of the equation
(20)(4)= 4(5x+1)
Simplify
80 = 20x+4
Flip the equation
20x+4 = 80
Subtract 4 from both sides
20x+4-4 = 80-4
20x = 76
Divide both sides by 20
20x/20 = 76/20
x= 3.8
There is one solution in this equation

The midpoint of 18.6 and 18.50 is 18.55.
What is a mean?
It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
18.6 and 18.5
The midpoint will be the average value.
Now,
Average = (18.6 + 18.5) / 2
Average = 37.1/2
Average = 18.55
Thus,
The midpoint is 18.55.

Answer:
The function through which given point passes is f(x) = 24 x - 12 .
Step-by-step explanation:
Given as :
The points are
,
= 1 , 12
,
= 2 , 36
now, slope of the line
Let The slope of line = m =
Or, m =
Or, m = 24
So The slope of line = m = 24
Now, equation of line in point-slope form
y - = m × (x -
)
Or, y - 12 = 24 × (x - 1 )
or, y - 12 = 24 x - 24
or, y = 24 x - 24 + 12
or, y = 24 x - 12
or , f(x) = 24 x - 12
So, The function through which given point passes is f(x) = 24 x - 12 . Answer
