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:
3
Step-by-step explanation:
5×3 =15
15-14=1
therefore the answer is 3
40/60=60/x...forty miles in sixty minutes is equal to 60 miles in 40 minutes.....40x=3600....x=90..90 minutes
