Answer:
The surface area of the candle is ![7.7\ in^{2}](https://tex.z-dn.net/?f=7.7%5C%20in%5E%7B2%7D)
Step-by-step explanation:
we know that
The surface area of the candle is equal to the area of its triangular base plus the area of its three lateral triangular faces
so
![SA=\frac{1}{2}(2)(1.7)+3[\frac{1}{2}(2)(2)]=7.7\ in^{2}](https://tex.z-dn.net/?f=SA%3D%5Cfrac%7B1%7D%7B2%7D%282%29%281.7%29%2B3%5B%5Cfrac%7B1%7D%7B2%7D%282%29%282%29%5D%3D7.7%5C%20in%5E%7B2%7D)
So basically, translating it to algebra:
3x = 4(x-2)
3x = 4x - 8
flip the like terms to the other sides so they become similar;
8 = 4x -3x
8 = x
And the number is 8!
Answer:
jumbo 23 oz, grande 16 oz
Step-by-step explanation:
Use g for grande and j for jumbo
The first equation: 28g + 33j = 1207
The second equation: 28g + 53j = 1667
Subtract the first from the second
28g + 53j = 1667
- 28g + 33j = 1207
Equal 20j = 460
j = 23
Put 23 in for j in either equation and solve for g:
28g + 33(23) = 1207
28g + 759 = 1207
28g = 448
g = 16
