You basically do 80-70 as the numerator of a fraction which should equal 10 and then the denominater should be 80 so you then do 10 divided by 80 and multiply your answer by 100 Hope This Helps You
The equation would be X +21+ 2X +17+ 2X +17 equals 180 when solved you get X equals 25
Answer:
4(x + 5) = 4x + 20 is C
2 + 7x = 7x + 2 is A
3(x multiplied 4) = (3x) x 4 is B

Answer:
Domain of a function as the possible values of x.
Step-by-step explanation:
When we define a function, we state to types of variable, the dependent variable and the independent variable.
If we have a function of the form
, here, x is the independent variable and y is the dependent variable, that is, y depends on x.
We define domain of a function as the possible values of x that is the independent variable. Thus, it is a set of all possible values of x such that the value of function f(x) or the value of y is defined.
To find the domain of a function, we should try to find all possible values x can take such that y is defined.
Example: In a function consisting of fraction we should choose the domain in such a manner that the denominator is not zero.
