Answer:
<h2>The answer is 3</h2>Step-by-step explanation:
Let the number be x
The statement
twice a number is written as
2x
The sum of twice a number and seven is written as
2x + 7
The result is 13
So we have
2x + 7 = 13
Subtract 7 from both sides
That's
2x + 7 - 7 = 13 - 7
2x = 6
Divide both sides by 2
That's
We have the final answer as
<h2>x = 3</h2>Hope this helps you
The whole field is square, and its total area is 25 acres.
It's divided up into 25 little sections.
Each little section is a square, and its area is 1 acre.
So the whole thing looks like a square tray with 25 little square blocks in it.
The blocks are in 5 rows, and there are 5 blocks in each row.
There are 16 blocks around the edge of the square tray, and 9 in the middle
that don't touch the edge.
Every block costs $1,200 to start out. But the ones around the edge are
more expensive. Anything on the edge costs an extra $150 for each side
of the little block that touches the edge.
Most of the 16 little blocks around the outside have only 1 side that touches
the edge. But the ones in the <em>corners</em> of the tray have 2 sides along the edge.
You may want to have a look at the picture I attached.
That should be plenty to put you in a position to work out the costs.
