If they are 36 together, and Marsha is twice Mary then do 2x+x=36
Saying that Marsha is twice Mary.
The equation of a line = y=mx+c
In the equation y = y, m = gradient, x = x, c = y intercept
So the equation = -2x+12 means the y intercept is 12
The constant of proportionality is 5/4 because it is coefficient of y=mx+b.

Answer:
D) 72
Step-by-step explanation:
The way to find the area of this figure easily is to break it down in regular shapes we know. You can then see it as two horizontal rectangles on top and bottom, measuring 6 x 4 each, then a vertical rectangle in the middle measuring 4 x 6.
So, overall, we have 3 similar rectangles measuring 4x6 or 6x4... which are equivalent.
The area of each of those 3 rectangles is 24 units (6x4).
Since we have 3 of those: 3 * 24 = 72.
