The answer is 24 because 8 times 3 is 24
Answer: Scale Factor = 3
Step-by-step explanation:
The top side of the blue triangle is equal to 2 and the top side of the red triangle is equal to 6. Therefore you hav to divide 6 by 2 to give you the scale factor which is 3. (Sorry I do not know if zoom factor is the same as scale factor)
For this case we propose a system of equations:
x: Let the variable representing the quantity of Granny Smith apples
y: Let the variable representing the number of Gala apples
According to the statement we have:
![x + y = 19\\0.25x + 0.30y = 5.10](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%2019%5C%5C0.25x%20%2B%200.30y%20%3D%205.10)
From the first equation we have to:
![x = 19-y](https://tex.z-dn.net/?f=x%20%3D%2019-y)
replacing in the second equation:
![0.25 (19-y) + 0.30y = 5.10\\4.75-0.25y + 0.30y = 5.10\\4.75 + 0.05y = 5.10\\0.05y = 5.10-4.75\\0.05y = 0.35\\y = \frac {0.35} {0.05}\\y = 7](https://tex.z-dn.net/?f=0.25%20%2819-y%29%20%2B%200.30y%20%3D%205.10%5C%5C4.75-0.25y%20%2B%200.30y%20%3D%205.10%5C%5C4.75%20%2B%200.05y%20%3D%205.10%5C%5C0.05y%20%3D%205.10-4.75%5C%5C0.05y%20%3D%200.35%5C%5Cy%20%3D%20%5Cfrac%20%7B0.35%7D%20%7B0.05%7D%5C%5Cy%20%3D%207)
So, Carl bought 7 Gala apples
On the other hand:
![x = 19-7 = 12](https://tex.z-dn.net/?f=x%20%3D%2019-7%20%3D%2012)
So, Carl bought 12 Granny Smith apples
Answer:
Carl bought 7 Gala apples and 12 Granny Smith apples
