Answer:
7 and 1/4 or 7.25
Step-by-step explanation:
28/4 = 7
1/4 = 0.25
7 + 0.25 = 7.25
<span>2x + 5y = 10
5y = -2x + 10
y = -2/5 x + 2
so slope = -2/5
</span><span>passes through the point (5, −4)
</span><span>y = mx + b
b = y - mx
b = -4 - (-2/5)(5)
b = -4 + 2
b = -2
equation
y = -2/5 x - 2

A could be 11.50x +15(y)=
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
