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>
The answer is 25 13/20 square feet.
In order to complete this operation, it is first best to change your mixed numbers into improper fractions.
7 1/8 = 57/8
7 1/5 = 36/5
Now that we have these, we can put them into the triangle formula.
A = 1/2bh
A = (1/2)(57/8)(36/5)
A = 1026/40
You can then simplify this fraction by dividing the top and bottom by a factor of 2.
A = 513/20
Then, because we know 20 goes into 500, 25 times, we can pull that out and be left with a remainder of 13/20.
A = 25 13/20
X+y=38 that’s your answer
3/4 divided by 1/5 = 3 3/4
Hope that helps :)
Answer:
283.5
Step-by-step explanation:
A=πr^2
A=π(9.5^2)
A=π(90.25)
π x 90.25=283.5 (rounded to the nearest tenth)
