<span>We are looking for the value of x if we know the value of y=0.8 and the equasion is: 4x + 8y = 40. First we separate what we don't know on the left side and what we do know on the right: 4x = 40 - 8y. we know y=0.8 so we put that in the equation and we get: 4x = 40 - 8*0.8. Now we have: 4x = 40 - 6.4=33.6. Finally, we divide the left side and the right side by 4 and we get: x=33.6/4=8.35. So x=8.35.</span>
Answer:
x+x=8
that's mean: 2.x/4 + 4.x/1 = 18/1
we find at least a common multiple of 4 and multiply the units by 4
2x + 16x = 72
18x = 72/:18
x = 4
L=N (because opposite angle of parllalogram is euqal)
4X-25= 3X+18
X =43
there for angle N=3×43+18
N=147
Now we know that the sum of the corresponding angle of a parllalogram is 180
N+M=180
M=180-147
M=33
