Answer: the box contained 9 square chocolates and 15 round chocolates.
Step-by-step explanation:
Let x represent the number of square chocolates contained in the box.
Let y represent the number of round chocolates contained in the box.
The box of chocolates contains square chocolates, which weigh 10g each and round chocolates which weigh 8g each. The combined weight of all the chocolates is 210g. It means that
10x + 8y = 210- - - - - - - - - - -1
The number of round chocolates is 3 less than twice the number of square chocolates. It means that
y = 2x - 3
Substituting y = 2x - 3 into equation 1, it becomes
10x + 8(2x - 3) = 210
10x + 16x - 24 = 210
26x = 210 + 24
26x = 234
x = 234/26
x = 9
y = 2x - 3 = 2 × 9 - 3
y = 18 - 3
y = 15

Answer:
You need four squares.
On the top left square, you put the number 20 over it, and the number 30 to it's left. Put the number 600 in the square.
Next, the bottom left square. But the number 8 on the left side of the square, and put the number 160 in the square.
Now, the top right box. put the number 4 over it, and fill it with the number 120.
Last, fill the bottom right square with the number 32.
Answer:
2^5 + 4^3 – 6x + 3
Step-by-step explanation:
Order the numbers by decreasing exponents. Start with the 2^5, since it has an exponent of 5. Next is the 4^3 since it has an exponent of 3. After that is -6x since it has an exponent of 1. 3 is last because it has an exponent of 1 and it has no variables attached.
