Answer:
x=8
Step-by-step explanation:
30-5x-10
-5x+30-10
-5x+40
-5x= -40
divide both sides by -5
-5x/-5= -40/-5
x=8
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
Answer:
Below in bold.
Step-by-step explanation:
Circumference = π * diameter
= π * 7
= 20.99 cm to nearest hundredth.
Radius of the circle = 1/2 * diameter = 7/2
= 3.5cm.
Area = π r^2
= π * 3.5^2
= 38.48 cm^2 to nearest hundredth.
