So we know that 22% of the mass off the chocolate bars is pecans, and that 4.5kg of pecans were used. To find the mass of nutty chocolate bars made with 4.5kg of pecans we can divide the 4.5 by 22 to find 1% of the weight of nutty chocolate bars produced, then multiply it by 100 to find the full weight in kg.
So 4.5/22= 0.205 (3dp), then 0.205x100=20.5kg of nutty chocolate bars produced.
Now to convert the kgs of chocolate bars to lbs, we multiply by 2.205 (as there is approximately 2.205 lbs to 1 kg).
So 2.205x20.5kg=45.203 lbs (3dp) of nutty chocolate bars produced on Tuesday.

Answer:
49 blue marbles
Step-by-step explanation:
From the question we are given;
- Total number of marbles = 58
- Blue marbles are 4 more than 5 times the red marbles
We need to determine the number of blue marbles;
Assuming the number of red marbles is x
Then, blue marbles will be 5x + 4
Therefore;
x + 5x + 4 = 58
6x + 4 = 58
6x = 54
x = 9
5x + 4 = 5(9) + 4 = 49
Therefore, the red marbles are 9 while the blue marbles are 49
Hence there are 49 blue marbles
Answer:
To isolate variables you can either:
- subtract from both sides
- add to both sides
- multiply both sides (by the same number )
- divide from both sides
These were basic.
Some more advanced ones are :
- raise both sides to the same exponent
- root both sides by the same root.
It has to be an inverse operation however, for all of these properties. And remember, they only work because they are done to both sides.
