Answer:

y= 1/2, x=1/2

Step-by-step explanation:

1st equation:

2x/3 + 3y/4 = 17/24    ... multiply it with 6

4x + 18y/4 =17/4

2nd equation:

   4x/3  + 5y/3 = 3/2 .....multiply it with 3

(-) 4x + 5y = 9/2

using elimination method

4x + 5y = 9/2

4x + 18y/4 =17/4

.........................................    <em> x cancel out's</em>

y/2 =1/4

y= 1/2

so x, 4x + 5y =9/2

x = (9/2 -5y)/4

x=(9/2 -5(1/2)/4

=1/2

The product of the base and height of a rectangle is the area. Can this statement be represented as a direct variation for the b
Flura [38]
Look at the formula A = b(h):  Area of a rect. = base times height.

In the unusual situation where you'd hold the area constant and vary b and h, then   A=bh could be re-written as

 A
---- = h    or  A/h = b.  In both cases we'd be working with inverse proportion,
 b                                   not direct proportion / variation.
