Answer:
The smaller addend is subtracted from the bigger addend
Step-by-step explanation:
Represent the two numbers with a and b such that a > b
So, the mathematical representation will be
Open the bracket
<em>This implies that the smaller addend (b) is subtracted from the bigger addend (b)</em>

<em>Take for instance; a = 6 and b = 4</em>
<em>This gives</em>

Answer:
21:50
Step-by-step explanation:
We need to find the ratio of 420 m to 1 km.
We know that,
1 km = 1000 m
So,
The ratio becomes,
So, the required ratio is 21:50.
G divides each median in the ratio of 2 to 1 (the longer side goes from G to the angle)
triangle AMN is similar to triangle ABC (why?)
AMN is a scaled version of ABC (by a factor of ⅔)
its area should be scaled by (⅔)^2
OK. I did it, and I have the solution.

The length of the deck is (5 + 2x) .
The width of the deck is (4 + 2x) .
If the deck didn't have that big hole in the middle where the pool is,
then its area would be
(5 + 2x) · (4 + 2x) .
When you multiply that all out, you get Area = 4x² + 18x + 20
and the question tells us that the area of the whole big rectangle is 90 yds² .
So we can write
4x² + 18x + 20 = 90 .
Subtract 90 from each side: 4x² + 18x - 70 = 0
Divide each side by 2 : 2x² + 9x - 35 = 0
You can use the quadratic equation to solve that and find out that
x = 2.5 yards, and that's what the question is asking you.

That makes the deck 10 yds high and 9 yds wide.
Total area of the whole big rectangle, (deck + pool ), = 90 yds².
Answer:
190,208
Step-by-step explanation:
732,178 + 167 = 732,345
732,345 - 542,137 = 190,208
