Answer:
commutative property
Step-by-step explanation:
With ratio to get the same ratio but bigger or smaller numbers you should double the ratio or half it. Dont know if this was any help :)
A*25+b*35=10250
a +b = 350 | * -25
25a + 35b= 10. 250
-25a -25 b= -8.750
------------------------------
10b = 1500
b=1500:10
b=150 tickets cost 35 $
a= 350-150
a= 200 tickets cost 25 $
Here are some examples of how the Quadratic Formula works:
<span>Solve <span>x2 + 3x – 4 = 0</span></span>
This quadratic happens to factor:
x2 + 3x – 4 = (x + 4)(x – 1) = 0
.
Then, as expected, the solution is <span>x = –4, x = 1</span>.
