sum means addition, so just add the three numbers...
12.6 +3.1 = 15.7 + 5.4 =21.1

Answer:
The first one because all characteristics mentioned in other options makes an scalene triangle but the first option makes isosceles triangle.
It must be an equal ratio- 2:3:7 = n:n:112
Now, to find the other numbers (n) in the ratio, we have to find the relationship between the two proportions.
To get from 7 to 112, we must multiply by 16. This is the relationship.
So, we must multiply both, the walnut and raisin cookies by 16 also.
2 x 16 = 32 = Raisin
3 x 16 = 48 = Walnut
Already known: 112 = Pinwheel
Now that we have all the data, we can make the ratio.
Raisin : Walnut : Pinwheel
32 : 48 : 112
Hope this helps! :)
1.49/6 = 0.248 per oz
3.59/13 = 0.276 per oz
lowest price is A. 6 oz for 1.49
Since we aren't told the length of the 3rd bar, focus solely on the lengths of the first 2 bars. Add together their lengths: 1.15 cm + 3.92 cm = 5.07 cm.
