Answer:
the answer is 11
Step-by-step explanation:
Due to the was its set up changes the way it looks. 5+(3+x)=19 and once its simplified 8+x=19 just subtract 8 from 19 and you get 11 so x=11.
<em><u>Answer:</u></em>
The answer is: a = -2.
<em><u>Step-by-step explanation:</u></em>
A = -2, because after graphing the equation in Desmos and plugging in various values for a, I found that when a = -2, the equation passed through the point (-3,12), so that's the answer. I'll attach a photo of the graph.

Answer:
Graph y=42.50 x and check that the graph is a straight line that goes through (0,0)
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
In this problem we have

so
therefore

Graph y=42.50 x and check that the graph is a straight line that goes through (0,0)
