Answer:
Share of A is $116 and Share of B is $84.
Step-by-step explanation:
Let the share of A be
Let the share of B be
Given:
$200 is shared between A and B
So,
Also given;
twice of A's share is less than 3 times than B's share by $20
Solution:
Now multiplying equation 1 by 3 we get,
Now Adding equation 2 and equation 3 we get
Now Substituting the value of x in equation 1 we get,
Hence, Share of A is $116 and Share of B is $84.
Answer:
C
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 3, 1) ← 2 points on the line
m = = -
y = - x ← equation of line
