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,

C. 120 students
10 + 15 + 20 +30 = 75%
100 - 75 = 25%
25% chose football which is 100 students
30% chose swimming
setup proportion:
25/100 = 30/x
25x = 100(30)
25x = 3000
x = 120
These are expression written as a function of sine, cosine and tangent. The value of x from the given function is 4.29
Trigonometry expression
These are expression written as a function of sine, cosine and tangent.
Given
tanx² - 1/3 = 0
Add 1/3 to both sides
tanx² - 1/3 + 1/3 = 0 + 1/3
tanx² = 1/3
x² = arctan(1/3)
x² = 18.44
x =4.29
Hence the value of x from the given function is 4.29
