Answer:
Total weight = 24 pounds
Number of helicopters = 3
Step-by-step explanation:
Small helicopters :
Weight = 3 pound
Weight of container = 15
Large helicopters:
Weight = 4
Weight of container = 12
3x + 15 = 4x + 12
3x - 4x = 12 - 15
-x = - 3
x = 3
Total weight of the container :
3(3) + 15
9 + 15 = 24 pounds
Hence, number of helicopters which will fit in either container is 3

Answer: infinite solutions
Step-by-step explanation:
(−3) (4) + (−3) (−3x) = 9x + −12
−12 + 9x = 9x + −12
9x − 12 = 9x − 12
9x − 12 − 9x = 9x − 12 − 9x
−12 = −12
−12 + 12 = −12 + 12
0 = 0
Answer:
14 books
Step-by-step explanation:
Let b = number of books at the beginning
She sold 1/2 of the books
b - 1/2 b
This is how many she had left
Then she bought 7
b - 1/2 b + 7
this equals 14
b - 1/2 b + 7 = 14
Combine like terms
1/2 b + 7 = 14
Subtract 7 from each side
1/2 b = 14-7
1/2 b = 7
Multiply each side by 2
1/2 b * 2 = 7*2
b = 14
She started with 14 books
