So you always want y in front of the equation no matter what so you have x +2y=5 so you take the x and you subtract it to both side making it 2y= 5-x so then you just have to take the 2 to both side so you have to divide it and you will get y= 5/2-x/2 so then to graph it you start with the b which is -x/2 so you go down -1 and over 2 and place your dot adn then go up 5 over 2 and then place you dot and connect them together
I believe x=15. Because you’ll just plug them in

Just had the question.
Answer:
4
Step-by-step explanation:
Given the data:
X : 20,25,30,20,30
Mean absolute deviation :
Σ(x - xbar) / n
n = sample size = 5
xbar = ΣX / n = (20+25+30+20+30) /5
xbar = 25
((20-25) + (25-25) + (30-25) + (20-25) + (30-25)) / 5
We take the absolute values, hence, negative signs are ignored :
(5 + 0 + 5 + 5 + 5) / 5
20 / 5
= 4
