Answer:
3-pack= 135 cupcakes
6-pack= 270 cupcakes
9-pack= 405 cupcakes
Step-by-step explanation:
Let's say that 3-pack = a, 6-pack =b and 9-pack = c
The company’s leaders want to divide the cupcakes so that 3-pack, 6-pack and 9-pack packages produced are the same. This translate to an equation of:
a=b=c
The factory has 810 cupcakes in total. The equation will be:
a*3 + b*6 + c *9= 810
3a + 6b + 9c = 810
If we substitute the 1st equation into the second(we can put b=a and c=a), the equation will become
3a + 6b + 9c = 810
3a + 6(a) + 9(a) = 810
18a= 810
a=45
Using the first equation, we know that we have 45 packages of each kind.
If there are 45 packages of 3-pack, the number of cupcakes go into 3-package will be: 3*45= 135 cupcakes
If there are 45 packages of 6-pack, the number of cupcakes go into 6-package will be: 6*45= 270 cupcakes
If there are 45 packages of 9-pack, the number of cupcakes go into 9-package will be: 9*45= 405 cupcakes
Answer:
8) $22
9) $33
Step-by-step explanation:
8) $75 to start, has 53 left. The difference of those is what he spent. 75 - 53 = $22
9) 165 divided equally in 5 months:
165 / 5 = 33
Answer:
undefined
Step-by-step explanation:
To find the slope given two points we can use
m = (y2-y10/(x2-x1)
= (0 - -4)/(7-7)
= (0+4)/(0)
4/0
This slope is undefined since we are dividing by 0
