6.48 divide by 6 and u will get the answer
In similar figures, the ratio between corresponding sides are the same.
![\frac{25}{35}=\frac{35}{49}](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B35%7D%3D%5Cfrac%7B35%7D%7B49%7D)
Simplify the two to see that they are equal.
The top and bottom of the left fraction are divisible by 5.
The top and bottom of the right fraction are divisible by 7.
![\frac{5}7=\frac{5}7](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D7%3D%5Cfrac%7B5%7D7)
Of course, the dimensions of that third picture would have to be this fraction.
Let's test these answers.
![\frac{5}6\neq\frac{5}7](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D6%5Cneq%5Cfrac%7B5%7D7)
⇒ A is not a solution
![\frac{30}{42}=\frac{5}7](https://tex.z-dn.net/?f=%5Cfrac%7B30%7D%7B42%7D%3D%5Cfrac%7B5%7D7)
⇒
B is the solution
(divide the top and bottom by 6)
Answer:
2 gallons of pure alcohol
Step-by-step explanation:
Let x represent the number of gallons of pure alcohol needed, and create an equation:
4(0.25) + x(1) = (x + 4)0.5
1 + x = 0.5x + 2
x = 0.5x + 1
0.5x = 1
x = 2
So, 2 gallons of pure alcohol should be added.
You do not want the "b" since two of the equations start off at 0 kites.
x=kites purchased
Kities : y=8x
Windy Kites: y=20x
From there, all you need to do is plug in the kite purchased number replacing x.
