Answer:
42°
Step-by-step explanation:
3x + 54° = 180° [Supplementary angles]
=> 3x = 180 - 54
=> 3x = 126

=> <u>x = 42</u><u>°</u><u> </u><u>(Ans)</u>
The answer is D because of the distributive property.
You would distribute x to 19 and -23 to make it equivalent to the given equation
I hope that helps!
The equation for this problem would be:
x+y = 16
Rearranging the equation, it can be expressed as:
y = 16 - x
To obtain ordered pairs, replace random values of x up to 16 to find the value of y. The ordered pairs are tabulated and the graph is shown in the attached picture.
