Price per box, P = $1.45 .
Money left, M = $1247 - $472.70 = $774.3 .
Let, number of boxes are x.
So,
![x = \dfrac{774.3}{1.45}\\\\x = 534\ boxes](https://tex.z-dn.net/?f=x%20%3D%20%5Cdfrac%7B774.3%7D%7B1.45%7D%5C%5C%5C%5Cx%20%3D%20534%5C%20boxes)
Therefore, they have to sell 534 more boxes.
Hence, this is the required solution.
x/20 = 21/14 (similar proportions)
x/20 = 3/2 (simplify by canceling out a factor of 7)
x = 30
The answer to this question is 7x+1
X=12. So this one says that it has 3 congruent sides so therefore it has to have 3 congruent angles. Here we have angle 2 and we have angle 60. Given the definition of triangle congruence, we can say that 60 is angle 2 and that the third angle is also 60 but it’s not relevant in this problem. So knowing that angle 2 is 4x+12 we solve for x by seeding that equal to 60 and then solving for x we get x=12. Hope this helps!!!!
