The missing blank is 2 because 7+2=9.
<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>
The numbers are a squence.
Yes they are similar. I believe one of them is smaller and upside. The size is different but the shape is the same!
Hope this helped :)
Answer:
94 and 33
Step-by-step explanation:
x = 3y - 5
x + y = 127
3y - 5 + y = 127 Substitute in (3y-5) for x
4y - 5 = 127
4y = 132
y = 33
127 - 33 = 94
