L = B + 105
H = L + 24.....H = B + 105 + 24 ...H = B + 129
H + L + B = 324
(B + 129) + (B + 105) + B = 324
3B + 234 = 324
3B = 324 - 234
3B = 90
B = 90/3
B = 30 <==Bart's marbles
L = B + 105
L = 30 + 105
L = 135 <=== Lisa's marbles
H = B + 129
H = 30 + 129
H = 159 <=== Homer's marbles
I believe its 765 meters.
75x15 (LxW)=255 meters
255x3=765 meters
10% maybe I think. Not completely sure tbh.
Answer:
The first answer is 14 marbles.
The second answer is 4 marbles.
Step-by-step explanation:
1. Add as many marbles needed to Carter's pile to match the amount of marbles with Sani's amount to get both amounts to be even.
2. The number of marbles you moved to Carter's pile to make both amounts even is the answer to the second question.
Remove unnecessary parenthesis.
-5k 3 - 6k +1 - 6k 2 + 5k (simplify each term) -15k - 6k + 1 - 12k +5k = -28k +1
Answer: 28k + 1
