W + 3 ≤ 10
This is the symbol for less than or equal ≤
w + 3 ≤ 10
w ≤ 10 - 3
w ≤ 7
Can't find an answer for w from the options.
Answer:
x+y=24 so we can say
x=24-y making 3x+5y=100 become
3(24-y)+5y=100
72-3y+5y=100
72+2y=100
2y=28
y=14, since x=24-y
x=10
So there are 10 3-point questions and 14 5-point questions.
