Answer: stacia would need 130 diamonds
Answer:
Step-by-step explanation:
(-1,5)....x1 = -1 and y1 = 5
(-5,-5)..x2 = -5 and y2 = -5
slope = (y2 - y1) / (x2 - x1)
slope = (-5 - 5) / (-5 - (-1) = -10 / (-5 + 1) = -10/-4 = 5/2 <===
<span>w - amount of wheat purchased
r - amount of rye purchased
12w+15r=18.30 /*2
15w+10r=16.75 /*3
24w+30r=36.60, subtract this equation from the other one
45w+30r=50.25
21w=13.65
w=13.65/21
w=0.65 is a cost per pound for wheat flour
From the first equation we have
r=(18.30-12w)/15
r=(18.30-12*0.65)/15
r=0.70 is a cost per pound for rye flour</span>
