Answer:
100 - 80 = 20
So 20lbs of turkey was eaten by kids, which means 60lbs was eaten by the adults
20 × 2 = 40
There are 40 kids
60 × 1 = 60
There are 60 adults
You would need to combine like terms to find your answer.
6x - 3 = 5x + 7
You would subtract 5x from both sides. Remember, x = 1x
x - 3 = 7
Lastly, you would add 3 to both sides.
x = 10
I hope this helps!
The real answer is 1691.3, however when rounded, 1692 deliveries.
First, we are going to multiply the pieces of wood by the length of each piece to find the total length she will need:

Next, we are going to convert 2262 centimeters to meters. To do that we are going to take advantage of the fact that 1 m=100cm:

Now, we just need to divide the total length of wood Marguerite needs by the length of each board of wood:

Since she will need full boards of wood, we must round 3.77 to its nearest integer 4.
We can conclude that <span>
Marguerite will need 4 boards of wood.</span>
