Answer:
<em>10a + 10b / 9x - 9y = 2 / 3</em>
Step-by-step explanation:
As we can see;
10 * ( a + b ) / 9 * ( x - y ) ⇒ 10a + 10b / 9x - 9y
This concludes that the top part of this equation is multiplied by 10 and the bottom by 9. To derive the solution, let us do the same with 3 / 5;
10a + 10b / 9x - 9y = 3 * 10 / 5 * 9
And simplify, to recieve;
10a + 10b / 9x - 9y = 30 / 45 = 6 / 9 = 2 / 3,
<em>Answer: 10a + 10b / 9x - 9y = 2 / 3</em>
Answer:
11 m by 18 m
Step-by-step explanation:
The area is the product of two adjacent sides of a rectangle. The perimeter is twice the sum of two adjacent sides, so that sum is (58 m)/2 = 29 m.
We want to find two factors of 198 that sum to 29.
198 = 1·198 = 2·99 = 3·66 = 6·33 = 9·22 = 11·18
Of these factor pairs, only the last one has a sum of 29.
The dimensions of the pool are 11 meter by 18 meters.
