Answer is B. No matter what the x or y will be the result will be 0. Anything multiplied by 0 is equal to 0.
For this case, we perform the conversions:
First roll:


We make a rule of three to determine the number of "c" boxes that can be packed with 300 meters of adhesive tape.
1 -----------> 4.2
c -----------> 300

You can pack 71 boxes.
Second roll:

We make a rule of three to determine the number of "c" boxes that can be packed with 70 meters of adhesive tape.
1 -----------> 4.2
c -----------> 70

You can pack 16 boxes.
Third roll:
1 -----------> 4.2
c -----------> 50

You can pack 11 boxes.
Thus, in total you can pack
Answer:
98 boxes
The answer would be D: $162 because $120 x 35% or (0.35) = $42 so $120 + $42 gives you $162
let h= history books
science books = s
h=2s there are 2 times as many history as science so to get them equal we double the science
h+s=81 there are 81 total history and science books
2s+s=81 substitute 2s for h in the above equation
3s = 81 combine like terms
s = 27
There are 27 science books
h=2s
h=2(27)
h=54
there are 54 history books
Answer:
53 degrees
Step-by-step explanation:
1) Base angle- 63.5 degrees: Given
2) Other base angle is- 63.5 degrees: Base Angle Theorem
3) Sum of angles in triangle: 2(63.5)= 127
180-127= 53
53 degrees
