1/2 (<em>b</em>x<em>h</em>)
1/2(5x4)
1/2(20)
10
find area of rectangle:
<em>b</em>x<em>h</em>
12 x 8

The number that has a 4 in the hundred places.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
A 4 with a value ten times less than the 4 in the number 123,469.
First, the value of the 4 in the number 123,469 can be found by separating each digit as:
123,469 = 100,000 + 20,000 + 3,000 + 400 + 60 + 9
Then the value of the 4 is 400.
Now we want a number that has a 4 with a value then times less than 400. Then we have
400/10 = 40
Then we want a number that has a 4 in the hundred places.

Answer:
x = 4, y = 12/5
Step-by-step explanation:
2x+5y = 20
6x-5y = 12
----------------- (+)
8x = 32 => x = 32/8 => x = 4
2·4+5y = 20 => 8+5y = 20 => 5y = 12 => y = 12/5
