Answer:
c=13 Perimeter=30
Step-by-step explanation:
c is equal to 13 so add all the sides together and you get 30
Answer:
this isn't a real equation..
Step-by-step explanation:
Answer:
(0,1)
Step-by-step explanation:
There are infinite number of (x,y) pairs in a line, so it should be easy to use any value for one of the coordinates (x or y) and find what the other coordinate should be. We can use a simple value that would make our solving easy, for example x = 0. We use this value to replace x in the equation of the line, and solve for y:
Therefore the pair (0,1) is a solution for the given equation.
You would substitute 0.8 in for y and to get the equation 4x+8(0.8)=40. Then, you would simplify and get 4x+6.4=40. Next you would isolate x by subtracting 6.4 from both sides and get the equation 4x=33.6 and then you would divide both sides by 4 to get x=8.4.
The answer is : x=8.4
