In this problem, we let x be the number of half gallons of milk the store bought, and x-12 be the remaining half gallonsWe use the equation profit = revenue-cost
88.08=4.02(x-12)-2.60x88.08=4.02x-48.24-2.6x1.42x=88.08+48.24=136.32x=136.32/1.42=96Hence, the number of half gallons of milk the store bought is 96
For this case, the first thing to do is to model the rectangular sandbox as a rectangular prism.
The volume of the prism is given by:
Where,
- <em>w: width
</em>
- <em>l: length
</em>
- <em>h: height
</em>
Therefore, replacing values we have:
We observed that:
Therefore, the sandbox is not completely filled.
Answer:
the sandbox will hold 
of sand
Jodi purchase is not enough sand to fill the sandbox to the top.
Answer:
when solving for multiplication
for instance
2*2=4
2+2=4
4+2=8
as 2*4,=8 after 4 you can add 2 to get the next multiple of 2
Same goes to the rest of other multiplication tables
Expand the factored expression (multiply all the terms back together), and see if it matches up with the original expression.
Answer:
4, 22 See below
Step-by-step explanation:
2x + y = 30
5x + y = 42
Subtract the first from the second
3x = 12
x = 4 so socks cost $4
Put that into one of the original equations
2x + y = 30
2(4) + y = 30
8 + y = 30
y = 22 slippers cost $22
