Answer:
You will be charged $5.5 in 55 minutes.
Step-by-step explanation:
Just multiply 0.10 by 55 and you get $5.5 dollars.
And no I don't think this is a Linear equation. Its not a linear equation because you have to set up a ratio to figure this out. Not a whole equation. So, Its more like a ratio
Answer:
1. Yes
2. Yes
Step-by-step explanation:
Leah wrote 2 different fractions with the same denominator. Both fractions were less than 1.
1. Can their sum equal 1?
Let Leah fractions be
and
Both these fractions have the same denominators and are less than 1. Find their sum:

2. Can their sum be greater than 1?
Let Leah fractions be
and
. Both these fractions have the same denominators and are less than 1. Find their sum:

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.
Answer: (-2, 8)
Explanation:
Plug x = -2 into the second equation. Isolate y.
5x+3y = 14
5(-2)+3y = 14
-10+3y = 14
3y = 14+10
3y = 24
y = 24/3
y = 8
We have x = -2 lead to y = 8.
Therefore, the ordered pair (x,y) = (-2,8) is the solution to this system.
