Answer:
The system of equation that represent this situations are;
Also 5 hats and 10 scarves can be prepared from 2 kg of yarn.
Step-by-step explanation:
Let number of hat Chevy makes be h.
Also Let number of scarves Chevy makes be s.
Given:
Total Amount of yarns = 2 kg
Total number of items = 15
Since Items need to make are hat and scarves.
Hence the equation can be represented as;
Again Given:
Each hat uses 0.2 kilograms of yarn.
each scarf uses 0.1 kilograms of yarn.
Hence the equation can be represented as;
Hence the system of equation that represent this situations are;
Now Solving these to find number of hats and number of scarves.
Multiplying equation 2 with 10 we get;
Now Subtracting equation 1 from equation 3 we get;
Now Substituting the value of h in equation 1 we get;
Hence 5 hats and 10 scarves can be prepared from 2 kg of yarn.
Answer:
pounds
Step-by-step explanation:
The customer will be charged extra if the weight of their suitcase is above 48 pounds.
Let the weight of the suitcase = w (in pounds)
Therefore, w above (greater than) 48 pounds is written mathematically as:
pounds
This is the inequality that represents w, the weight of the suitcase in pounds, that will have an extra charge.
