Unfortunately, I can't do it on a graph here, but I will do it algebraically.
The solution on the graph will be the point of intersection of the two lines representing the equations.
y + 2.3 = 0.45x . . . . . (1)
-2y = 4.2x - 7.8 . . . . . (2)
From (2), y = 3.9 - 2.1x
substituting for y in (1), we have:
3.9 - 2.1x + 2.3 = 0.45x
2.55x = 6.2
x = 6.2/2.55 = 2.4
y = 3.9 - 2.1(2.4) = 3.9 - 5.04 = -1.2
Therefore, solution is (2.4, -1.2)
Answer:
2 2/9
Step-by-step explanation:
2 divided by 9/10 = 2/1 / 9/10
2/1 x 10/9 = 20/9 = 2 2/9 or 2.222..
Answer:
there were 165 chairs
Step-by-step explanation:
as the total chair in huda s sides were 14 + 1 chair she was sitt ing = 15
then there were total 10 rows + 1 row in which she was sitting =11
total chairs = 11× 15 =165
