Answer:
Área: 6x2=12, 2x3=6, 10x3=30, 30+6+12=48; <u>área = 48</u>
Perímetro: 10+3+6+2+6+5+2+3+2+3=42; <u>perímetro = 42</u>
1) In a proportion: y/x=k
k is your constant of proportionality.
x is your independent variable and y is your dependent variable.
Since you need 3 oz of flour for each 2 oz of sugar, y=3 and x=2.
So k=1.5 (3/2)
3)
a) y/x as a showed above. This question is very similar to #1.
b) y/x=k
