The answer is the last one bc 2.55 divided by 8 is 0.21
Answer:
The unit price at Price-Club is $0.2158 per ounce.
The unit price at Shop Mart is $0.2925 per ounce.
Step-by-step explanation:
Price Club:
12-ounce box of crackers for $2.59
So
12 ounces - $2.59
1 ounce - x
![12x = 2.59](https://tex.z-dn.net/?f=12x%20%3D%202.59)
![x = \frac{2.59}{12}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B2.59%7D%7B12%7D)
![x = 0.2158](https://tex.z-dn.net/?f=x%20%3D%200.2158)
The unit price at Price-Club is $0.2158 per ounce.
Shop Mart:
1-pound box of crackers for $4.68.
1 pound is 16 ounces. So
16 ounces - $4.68
1 ounce - x
![16x = 4.68](https://tex.z-dn.net/?f=16x%20%3D%204.68)
![x = \frac{4.68}{16}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B4.68%7D%7B16%7D)
![x = 0.2925](https://tex.z-dn.net/?f=x%20%3D%200.2925)
The unit price at Shop Mart is $0.2925 per ounce.
Answer:
The standard form of the equation is 2x + 5y = -1
Step-by-step explanation:
To find this equation in standard form, we first need to find the slope of the line. We can do that by using the slope formula with the two points.
m(slope) = (y2 - y1)/(x2 - x1)
m = (1 - -3)/(-3 - 7)
m = 4/-10
m = -2/5
Now that we have the slope, we can use that along with the point in point-slope form
y - y1 = m(x - x1)
y - 1 = -2/5(x + 3)
Now that we have that, we can solve for the constant and rationalize the denominators.
y - 1 = -2/5x - 6/5
2/5x + y - 1 = -6/5
2/5x + y = -1/5
2x + 5y = -1
