Answer:
30 each of 23% bars and 18 each of 79% bars
Step-by-step explanation:
If x is the number of 1 kg 23% copper bars, and y is the number of 1 kg 79% copper bars, then:
x + y = 48
0.23x + 0.79y = 0.44(48)
Substituting and solving:
0.23x + 0.79(48-x) = 0.44(48)
0.23x + 37.92 - 0.79x = 21.12
16.8 = 0.56x
x = 30
y = 48 - x
y = 18
You need 30 each of 23% bars and 18 each of 79% bars.
The median of the numbers would be 7.5

Answer:
4
Step-by-step explanation:
The distributive property does not appear to be involved in this question.
Let n represent the number of Noah's pencils. Then Andrew's total is ...
3n +5 = 17
3n = 12 . . . . . subtract 5 from both sides
n = 4 . . . . . . divide both sides by 3
Noah has 4 pencils.
