16 is 20 percent of the number 80.
In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100.
Therefore, let's find the number 16 is 20% of .
Let
x = the number
Therefore,
20% of x = 16
20 / 100 × x = 16
20x / 100 = 16
cross multiply
1600 = 20x
divide both sides by 20
x = 1600 / 20
x = 80
Therefore, the number is 80

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
By definition, if two lines are parallel then their slopes are equal.
If we have the following line:
Whose slope is
So, a line parallel to it has a slope
Therefore, the equation is of the form:
If the line passes through point we can substitute in the equation and find "b":
Finally, the equation is:

Answer:
y=x+2
Step-by-step explanation:
parenthesis, exponents, multiplication, division, addition, subtraction.
(14)/(7)(5)(-3)^2 solve exponent first and then the multiplication part (7x5)
(14)/(35)(9) 14 divided by 35 is .4
(.4)(9)=3.6 .4 multiplied by 9 is 3.6 <- that's the answer for 7
remember parenthesis first so we will do 6-1 first which is 5. after parenthesis, well do exponents. 5^2 is 25.
we will finish the big parenthesis which is the brackets, and 30-25=5. now it's 5 +5=10<- that is the answer for 9. Do I need to explain more/ if not i hope this helps you better understand this.
